Scout (Jean Louise) Finch
Narrator and protagonist
Six to nine years old across the novel, Scout is a tomboyish, fiercely literate narrator whose first-person voice sits at a productive distance from her child-self. Lee uses a dual perspective: the child’s bewildered observation and the adult’s retrospective judgement. Scout’s moral arc moves from literal, tit-for-tat thinking towards Atticus’s ethic of empathy.
”Until I feared I would lose it, I never loved to read.”
Atticus Finch
Father, lawyer, moral centre
A widowed state legislator and defence attorney, Atticus is principled, patient and almost impossibly self-controlled. Critics since the publication of Go Set a Watchman have contested the "saintly" reading, but in Mockingbird he functions as a moral yardstick - teaching courage without confidence of victory, empathy before judgement, and the separation of public duty from private feeling.
“The one thing that doesn’t abide by majority rule is a person’s conscience.”
Jem (Jeremy) Finch
Scout’s older brother
Four years older than Scout, Jem undergoes the novel’s most visible loss of innocence. His fascination with Boo Radley, his growing admiration of Atticus and his shattered faith in Maycomb after Tom’s conviction trace a more bruised coming-of-age than Scout’s. His broken arm, mentioned on page one, becomes the novel’s framing wound.
”I always thought Maycomb folks were the best folks in the world…”
Tom Robinson
The accused
A hard-working, physically disabled Black labourer, Tom is falsely accused of raping Mayella Ewell after he responds to her loneliness with kindness. His disabled left arm makes the alleged assault physically impossible, yet the jury still convicts. His death, shot "seventeen times" while trying to escape prison, exposes the hollowness of Atticus’s faith in appeal.
”I felt right sorry for her.”
Arthur "Boo" Radley
Reclusive neighbour
The novel’s second "mockingbird". Boo is first a Gothic childhood legend - a figure of rumour and dares - before emerging as the silent protector who stitches Jem’s trousers, leaves gifts in the oak, and finally kills Bob Ewell to save the children. His one spoken line in the novel ("Will you take me home?") is devastating in its quietness.
“Atticus, he was real nice… Most people are, Scout, when you finally see them.”
Calpurnia
The Finches’ housekeeper and Black maternal figure
Calpurnia is bilingual in dialects - "white" at the Finches, African-American Vernacular English at First Purchase Church - embodying the double consciousness Black characters must navigate in Maycomb. She disciplines Scout, models rigorous moral expectations, and offers the children their only serious exposure to Black community life.
“Don’t matter who they are, anybody sets foot in this house’s yo’ comp’ny.”
Bob Ewell
Antagonist
The unemployed, alcoholic patriarch of the Ewell family, Bob represents the "poor white" demographic whose only social currency is whiteness. Lee uses him to separate racism from ignorance (Atticus distinguishes the Ewells from the Cunninghams) and to show how racial hierarchy props up otherwise failing masculinities.
Bob Ewell attacks the children on Halloween; Boo Radley intervenes.
Mayella Ewell
Complicated victim-accuser
Nineteen, isolated, and abused by her father, Mayella is both victim and perpetrator - a figure through whom Lee examines how gender and class intersect with race. Her seven red geraniums, tended "as carefully as Miss Maudie Atkinson", register a yearning for beauty the novel treats with uncomfortable sympathy before her false testimony condemns Tom.
Atticus: “Who beat you up? Tom Robinson or your father?”
Aunt Alexandra
Atticus’s sister
Alexandra arrives during Part Two to drill Scout in "ladylike" behaviour and enforce a hereditary sense of Finch family pride. She represents the Southern aristocratic code Atticus has partly rejected; her tea-party grace under pressure after Tom’s death reveals a harder decency than Scout expects.
“Jean Louise, stop scratching your head.”
Dill (Charles Baker Harris)
Summer friend
Based on Lee’s real childhood friend Truman Capote, Dill brings imagination and melodrama to the Boo Radley games and weeps openly in the courtroom. His tears function as the novel’s emotional interpreter for readers who might otherwise read the trial as procedural.
”It was just him I couldn’t stand… that old Mr Gilmer doin’ him thataway…”
Miss Maudie Atkinson
Neighbour and Atticus’s ally
A progressive Baptist widow, Miss Maudie articulates the mockingbird symbol, defends Atticus’s character to the children, and after her house burns down greets the loss with humour. She is the adult female voice the novel most trusts.
“Mockingbirds don’t do one thing but make music for us to enjoy.”
