Main characters
The following list features characters that are considered fundamental to the series' storylines, consisting of the central group deemed as "the Liars" and the main antagonist "A."

Spencer Hastings
Considered the "de facto leader" of the group, Spencer Hastings, portrayed by Troian Bellisario, is intelligent, extremely ambitious, and strives for perfection in everything she does in an attempt to live up to the high expectations of her parents. Spencer's biggest rival is her older sister, Melissa, and the two are constantly fighting over something. Their relationship is often strained by the fact that Spencer has a habit of crushing on Melissa's boyfriends. In the first season, she begins a relationship with fellow student and strained Rosewood student Toby Cavanaugh. Throughout the series, Spencer is revealed to be the biological daughter of Mary Drake and the sister of Charlotte Drake.

Aria Montgomery
Considered the "alternative" one of the group, Aria Montgomery, portrayed by Lucy Hale, is more outgoing in fashion and what she sees as acceptable behavior. She moves back to Rosewood with her family after living in Iceland for a year. Before Alison's death, she and Alison discovered that Aria's father was having an affair with one of his former students, Meredith, who became his coworker at Hollis College. Alison encourages Aria to tell her mother the truth, but instead, Aria reluctantly agrees to keep her father's secret. On top of that, she finds herself involved with her high school English teacher, Ezra Fitz, after making out with him in a pub bathroom and discovering he was her English teacher on the first day of school.

Hanna Marin
Pretty and fierce, Hanna Marin, portrayed by Ashley Benson, is the diva and "it girl" of the group, having taken Alison's place as the most popular girl at Rosewood High. Prior to Alison's death, Hanna suffered from bulimia, which Alison frequently teased her over. Since her parents divorced, Hanna permanently lives with her mother. She feels betrayed by her father, who has remarried, and she does not get along well with his new wife and daughter. When Hanna's mother falls upon financial hardship, she steals thousands of dollars from the bank she worked at, which Hanna is forced to keep a secret.

Emily Fields
The "jock" of the group, Emily Fields, portrayed by Shay Mitchell, is a highly competitive swimmer, considered the star of Rosewood's swimming team. She is shown as a sweet and shy girl. For a short time, Emily lives with Hanna, after her mother moves to Texas to live with Emily's father, who is stationed in Fort Hood. She begins to question her sexuality because of her feelings for Alison, but later accepts the fact that she is a lesbian and starts to date girls. She eventually begins a relationship with Sara Harvey, until she discovers that she is an ally of the antagonist.

Alison DiLaurentis
The former "queen bee" of her clique, Alison DiLaurentis, portrayed by Sasha Pieterse, used to be the most popular girl in school before her disappearance and alleged death. Although she cared for her friends, she enjoyed using their deepest secrets against them to keep them in line. Charming and manipulative, Alison was skilled at finding ways to blackmail everyone, and many people hated her. She knew everybody's secrets, but since she's been gone her friends are beginning to realize how little they really knew about her. She is revealed to be alive and on the run from "A."

Mona Vanderwaal
A former "unpopular" girl at Rosewood, Mona Vanderwaal, portrayed by Janel Parrish, longed to be accepted into Alison's group and was continuously mocked by her. After Alison's disappearance, Mona befriended Hanna and they underwent an "extreme makeover" together; as a result, they both became popular students. When "A" appears, Mona becomes jealous of Hanna rekindling her friendships with the other Liars. She dislikes Caleb and makes attempts to break Hanna and Caleb up, though to no avail. She becomes romantically involved with Noel, much to Hanna's disapproval, but is later dumped by him for Jenna. When "A" begins sending Mona threatening notes, she grows closer to the Liars. In the second-season finale, she is in fact revealed to actually be "A" when she and Spencer travel to the Lost Woods Resort to uncover "A"'s lair. She is committed to a mental institution, Radley, after being diagnosed with borderline personality disorder.

"A"
The main antagonist, "A" is stalking and torturing the Liars in relentless and creative ways and also threatens their friends and family. In the second-season finale, it is revealed that Mona is "A". She is also the one who stalked Alison before her disappearance. However, when she is sent to Radley sanitarium, she is visited by CeCe Drake, who offers her a partnership and takes over the team of "A"s, known as the A-Team. The team consists of Mona, Toby, Spencer, Sara, Lucas, Melissa, Wilden, Jenna, Noel, and Wren. Five years later, Alex Drake takes over and becomes Uber A, known as "A.D.", and forms the A.D. Team, consisting of Jenna, Sydney, Aria, Wren, Mona, and Mary.

He blames Aria for the trouble between their parents. Mike accidentally discovered that Jenna and Garrett knew each other when he stole a pot made by Jenna from Garrett's house. Mike reveals to Aria that the only reason he punched Ezra was because after Ezra and Aria announced they are a couple, he feared what Byron would have done to hurt Ezra judging by the look on his face and thought, "better I do it, than him."

He quit his teaching position at Rosewood just before Noel threatened to expose Aria and Ezra's relationship.

Their relationship seems to be going smoothly until Ezra's younger brother Wesley "Wes" drops by unexpectedly.

Spencer and Melissa's father's gun goes missing, and Spencer fears Melissa took it. Even though Melissa didn't take the gun, her parents still feared that she killed Alison through jealousy, so her mother hired a private investigator to watch her.

She was taken into police custody where she admits to knowing who killed the girl in Ali's grave and tells them Ali is alive and that she can prove it. Later that night, she escapes and takes a police car. She heads to New York where she asks for Ali's help. It is revealed that Ezra was paying CeCe for information which is why she was in Ravenswood. Ali asked her to wear the Red Coat to distract "A" so she could turn off the saw. Alison gives CeCe her plane ticket and CeCe boards a plane to France, under the alias "Vivian Darkbloom". In "Game Over, Charles", it is revealed that CeCe is actually "A" and was born as Charles DiLaurentis. CeCe was admitted to Radley Sanitarium as a child, after a misinterpreted incident involving Alison as a baby. Their parents told Jason that she was imaginary. It is claimed that Charles committed suicide at age 16 so that CeCe could transition into Charlotte DiLaurentis. Mr. DiLaurentis was unaware of CeCe/Charlotte's existence and Charlotte eventually began dating Jason to get closer the family and became CeCe Drake. CeCe/Charlotte was given privileges to leave Radley to attend the University of Pennsylvania, and one night Bethany stole her clothes and escaped to hurt Mrs. DiLaurentis. CeCe stumbled upon Alison and hit her, believing it was Bethany. Later, CeCe made friends with Mona, who told her all about the "A" game and the Liars, and CeCe offered her a partnership and she helped CeCe escape, where she became "A". Sometime after this, CeCe hired Sara Harvey to become her accomplice by dressing up as Red Coat and The Black Widow. CeCe was also Red Coat, being the one to watch Mona dig up the grave, don the Emily mask and attend the Hoe Down. After declaring game over, Charlotte was admitted to a sanitarium for treatment. Once the Liars discover who she is, she ends the game. Five years later, Alison petitions the court to release Charlotte, asking the girls to testify in her favor. Charlotte is released and brought home to Alison. However, the next morning her body is found, seemingly having jumped from the bell tower, until the police discover that Charlotte was already dead upon "being thrown".
