Susan to Greg when he was in a tough situation in the first film.

Susan Heffley (known as Ann Heffley in the online book), is the wife of Frank Heffley and the mother of Rodrick, Greg, and Manny Heffley. She is a former member of the PTA who once worked as a preschool teacher, and once was the substitute teacher in Greg's class. She normally appears as a major character in the Diary of a Wimpy Kid series, but she plays the main antagonist in Dog Days, Double Down, and the film adaptation of The Long Haul.

In the first three Diary of a Wimpy Kid movies, Susan is played by Rachael Harris, with that role being filled by Alicia Silverstone in the fourth movie in 2017.


Susan is a rather loving and caring mother, but she constantly embarrasses Greg and Rodrick (mainly Greg) and appears to never care. Susan obviously knows very little about older children and often humiliates, embarrasses, and ignores Greg and Rodrick, much to their dismay. She thinks everyone would understand about Greg's accident, even if the kids in his grade don't. Also, she shows immense favoritism towards Manny. Susan has been shown to have very neat handwriting, as whenever her writing is shown it is very fancy, almost in a 1960s fashion. She constantly tries to pull the family together, by getting Frank and Greg accustomed to Rodrick's band, trying to get Greg, Rodrick and Manny to become close to Frank, and attempting to get Greg to enjoy reading "real" literature, but none of her plans ever seem to work, and often end up in rather disastrous consequences for Greg and Rodrick and sometimes even backfiring on her completely. At one point during the Deep End, Susan tried to get the family to attend the Pool Party at Camper's Eden for a special night until a group of kids flipped them over when they got onto an airplane tire. The incident apparently scarred Susan physically and mentally so much that she immediately gave up on the pool party. Additionally, she puts individual desires below family desires; she rarely lets anyone in the family come to a decision about an outing or purchase without her permission, resulting in her always winning. Susan is also shown to not accept criticism very well which may be the reason why she refuses to listen to anyone who point out flaws in her thinking.

According to Greg, she completely spoils Manny, giving him many privileges to Manny that she never gave to Greg or Rodrick when they were younger, such as bringing toys to church to keep himself entertained and buying new clothes for Manny while giving Rodrick's old clothes to Greg. Susan even allowed Manny to verbally abuse Greg by calling him "Ploopy" (though she may have not paid too much attention to the whole matter because Greg interrupted her in the middle of a call and thus she was angry) and only put a stop to it when Greg called Manny, "Ploopy" for revenge. Susan dotes on Manny to the point where she doesn't scold or punish him at all. She even once drove all the way to Manny's pre-school just to cut an extra-slice on his sandwich. She also appears to give Manny a lot of money, even when he potties without being told (although this is not a big thing since he is already potty-trained) and also if his brothers swear in front of him, according to Greg he got up to $150 in American dollars. However, it's shown sometimes that Susan will correct Manny if she sees it necessary: for example when Manny destroys Greg's gaming console, Susan talks with Manny and makes him realize that what he did was wrong, leading Manny to make an aluminum foil ball with toothpicks to compensate Greg (though Susan eventually let him throw it to the trash as Rowley got injured with it) and while she doesn't punish Manny when he cuts all electricity on their house to the point they nearly starved just because she didn't teach him how to tie his shoelaces, Susan is seen to not be so happy with Manny when she teaches him how to tie his shoelaces. She also tries to refuse a pig that Manny won by pure chance (when he just happened to guess the weight of a hog right) because they only entered for fun. Sometimes she would ruin the party (for example, she tried to turn the wild party into a carnival-styled, non-violent party, much to the boy's anger) and not listening about Greg for kids these days.


Susan has a more different look from the rest of her family in the online and book version. Like her husband, she has an egg-shaped face. She wears large glasses that cover up her eyes. She has appeared in the series without glasses while sleeping. She has tall dark round hair (not used by anyone else) and she wears normal pants, either sweatpants or slim jeans, and a sweater. In The Third Wheel, a flashback photo shows she didn't need to wear glasses and had longer hair.

In the movie, Susan is played by Rachael Harris and, just like other members of her family, has brown hair and a flawless complexion. She also appears with her trademark glasses. Unlike in the book and online version, she wears make-up in the movie. She is played by Alicia Silverstone in The Long Haul movie.



Susan was born to Gramma and Grampa and had 4 sisters. Susan was born in a different state. Her favorite book was Little Women. Much of her childhood remains unclear, though it is implied she was raised on a farm she hinted she did not often get along with her siblings that much. She mentioned in The Deep End that she met some of her best friends at summer camp.

Middle School Basketball team

Susan played for her Middle School basketball team The "Huskies" as a backup point guard. In one of her matches the regular point guard got hurt so with the score tied in the fourth quarter she had to go and take her place. She did well, but with the clock winding down she got double-teamed, so she had to heave the ball up at the buzzer and her shot didn't succeed. Later, Susan told her son, Greg, that she's glad it happened because it taught her how to deal with failure.

Teenage Years

She attended summer camp and played the French Horn in high school, the rest is unknown.


Frank and Susan in their Honeymoon

Frank and Susan in their Honeymoon

After finishing high school, she met Frank Heffley and fell in love with him and they went to Isla de Corales in their honeymoon they got married in and lived in a small apartment and after that, she gave birth to Rodrick Heffley.

Some time later, Greg was born. She let him sleep in the dresser drawer while Rodrick slept in a crib. They moved to their current house in Plainview on an unknown date. Years later, Manny Heffley was born.



  • Her first name is "Ann" is the original online version.
  • She is known for taking things literally, as suggesting School uniforms in The Third Wheel when Greg asks for new clothes and disconnecting anything that uses electricity in Old School
  • Susan serves as the main antagonist in Dog Days.
  • In the book, her glasses covering up her eyes are similar to Marcie from Peanuts.
  • Susan has 4 sisters: Aunt Gretchen, Aunt Audra, (also known as Audra Heffley), Aunt Cakey, and Aunt Veronica, mentioned in Hard Luck.
  • Just like her mother, grandmother, and great-grandmother, she appears to like and favor Manny more than Greg and Rodrick.
  • In The Last Straw, she told Greg that Holly Hills wasn't potty-trained at 4 years old.
  • Due to letting Manny have his own way always, letting Greg ride in a stroller, and allowing Rodrick to make funky music in his band, she seems to occasionally spoil her kids, though not usually.
  • Similar to her second oldest son Greg, Susan doesn't appear to get along that well with her siblings.
  • In Cabin Fever, Susan is shown to be very impatient when waiting in lines. When Greg wanted to take pictures with characters at theme parks, Susan would walk up to the front and take a picture of the character and a random kid with it which Greg explains how their photo album is often filled with random people. She even went as far as forging Kenny Centazzo's signature on Greg's Tower of Druids copy which Greg didn't realize until he wanted to sell it.
  • Susan once dyed her hair blonde as revealed in a game that the family was playing in The Long Haul.
  • Susan might not originally be from Greg’s city since it is stated that most of her extended family comes from other states.
  • She can't speak Spanish at all and is very bad at it, as shown in The Long Haul when she thinks that the statement "What's your name" is "tè amò" (although its real meaning is "I love you.", with "what's your name" being "Como te llamas" in Spanish) She also thinks "Tengo hambre" is "tango hamburgers," however it actually means "I'm hungry." Despite this, she tries to teach her sons Spanish, although Manny is the only person who ends up learning anything.
  • She seems to have a habit of using the word "real" to refer to stuff she appreciates, as though what she disapproves of is somehow not authentic. For example, she calls fast food "not real food" because she thinks it's unhealthy and she calls books that are not storybooks "not real literature".
  • In the Getaway, she takes the Heffley Family on a vacation on a tropical island resort, Isla de Corales, in which she and Frank went there on their last honeymoon.
  • Susan's age is not revealed in the books however in the second film, Greg mentioned that Frank and Susan could be at least 40.
  • Sometimes her personality is a bit inconsistent and hypocritical. For instance, she tells Greg to be honest but then tells a lie, acts like she doesn't believe in psychic abilities but then says that Gramma has them, or tells her sons not to yell but then yells at them.
    • A good example of this is during Old School when Greg tried to sell water to volunteers working at the city park only for Susan to say it was tacky to profit off of them. However later she was seen buying Girl Scout cookies when the Girl Scouts arrived despite what she said earlier. She was also the first to break the electronic free policy to search for Greg when he went missing even though she was the one who petitioned it in the first place.
      • In Wrecking Ball, she doesn't appear to take criticism very well. When the Heffley's attempted to sell their house, Susan was easily offended by the critiques other people made about their house while Greg took it rather well.
  • In Cabin Fever, Susan didn't believe that Manny took her glasses. This shows that she lets Manny have his own way and believes he is innocent of anything.
  • In Rodrick Rules, Susan didn't believe that Manny stuffed a chocolate-chip cookie in the disk drive. This is another way that she lets Manny have his own way.
  • Aside from working as a preschool teacher and writing parenting articles for the local newspaper, it's unknown what Susan did for a living prior to eventually going back to school to get her master's degree. In the journals prior to when Susan decided to go back to school full-time (instead of just part-time), she appeared to mostly stay at home. Whether this means she was a stay-at-home or work-at-home mom is unclear.
  • Her maiden name (her last name before she and Frank got married) has never been revealed.
  • Her email in the film is susanheffley1@gmail.com.
  • She treats Manny like he is king.
  • In Big Shot, it's revealed she's been wearing glasses since middle school, possibly earlier than that.
