This is a list of characters from Ulysses by James Joyce.

• Leopold Bloom is a protagonist and hero in Joyce's Ulysses. His peregrinations and encounters in Dublin on 16 June 1904 mirror, on a more mundane and intimate scale, those of Ulysses/Odysseus in Homer's epic poem the Odyssey. The character was inspired by James Joyce's close friend, Aron Ettore Schmitz (Italo Svevo), author of Zeno's Conscience.
• Molly Bloom, the wife of main character Leopold Bloom, she roughly corresponds to Penelope in the Odyssey. The major difference between Molly and Penelope is that while Penelope is eternally faithful, Molly is not.
• Stephen Dedalus is James Joyce's literary alter ego, appearing as the protagonist and antihero^[1] of his first, semi-autobiographical novel of artistic existence A Portrait of the Artist as a Young Man and an important character in Joyce's Ulysses. Stephen Dedalus appears in Ulysses as the character who corresponds to Telemachus; less overtly, he embodies aspects of Hamlet. He is the protagonist of the first three chapters. Subsequently, Leopold Bloom is introduced, and Stephen's interactions with Bloom and his wife, Molly, form much of the final chapters' substance.

• Almidano Artifoni, an opera singer.
• Mrs. Yelverton Barry has been described as "one of the fantasized sadistic women of 'Circe'"^[2] who accuse Bloom in the courtroom scene of having made sexual advances—in her case, of writing to her claiming to have observed her "peerless globes" in the Theatre Royal, and offered to send her a work of fiction by a Monsieur Paul de Kock.^[3] She also features as a character in the play, Ulysses in Nighttown.^[4]
• Mrs. Bellingham is one of the fantasized sadistic women of the "Circe" chapter^[5] who accuse Bloom in the courtroom scene of having made sexual advances—in her case, of sending her a letter asking her to "commit adultery at the earliest possible opportunity".^[6] She also features as a character in the play, Ulysses in Nighttown, and was played by Bernadette McKenna and Maire Ni Ghrainne at the Abbey Theatre.^[7]
• Richard Best is a character based on Celtic scholar Richard Irvine Best. Best was an acquaintance of J. M. Synge and Joyce. Best was depicted as one of the characters in the National Library scene in Episode 9 "Scylla and Charybdis".^[8] Best was known to have disapproved of Joyce's characterisation of him.^[8]
• Milly Bloom is Molly and Leopold's fifteen-year-old daughter, who does not actually appear in Ulysses other than through verbal recollections and letters. The Blooms send Milly to live in Mullingar and learn photography. She is dating Alec Bannon in Mullingar.
• Edy Boardman – a prostitute.
• Blazes Boylan is the manager for Molly Bloom's upcoming concert in Belfast. Boylan is well known and well liked around town, but comes across as a rather sleazy individual, especially regarding his attitudes toward women. Boylan has become interested in Molly, and they have an affair during the novel.
• Josie Breen is a former love interest of Leopold. He encounters her in Dublin, and then later in the "Nighttown" sequence where Bloom re-lives his affection for her. Josie's husband Denis is something of a laughingstock and is in poor mental health.^[9]
• Denis Breen is the husband of Josie Breen and is a figure of fun. A person unknown sent him a postcard with "U.p: up" written on it and he seeks to take a libel action for ten thousand pounds. Leopold states that Josie's marriage to Denis was a case of "beauty and the beast".^[6][10]
• Cissy, Jacky, and Tommy Caffrey: Cissy Caffrey is a friend of Gerty MacDowell and encounters Bloom on Sandymount Strand. She appears again in the "Nighttown" sequence, apparently as a lady of the night. Jacky and Tommy are her two younger brothers who she is minding at Sandymount.^[11]
• Nurse Callan is a nurse at the National Maternity Hospital. She is described as a "virgin" and attends to a local woman, Mina Purefoy. She is described as brushing a Dr. O'Hare's coat attentively.
• Private Carr – a British soldier.
• The Citizen is an old Irish nationalist with xenophobic and anti-semitic views who engages in an argument with Leopold in Barney Kiernan's pub, ultimately throwing a biscuit tin at him. "The Citizen" is an important figure in the "Cyclops" episode of the novel. The character has been described as having characteristics not only of the mythological Cyclops but also of the Irish epic figure Finn McCool.^[12] "The Citizen" is, in part, a satirical portrait of Irish nationalist (and Gaelic Athletic Association founder) Michael Cusack^[13] and Joyce's portrayal operates to expose what one critic called the "xenophobic ideologies of radical Celticists".^[14]
• Martha Clifford is a correspondent with Leopold Bloom, who according to some scholars is a pseudonymous identity for over a half a dozen other characters.^[15]
• Bella Cohen is the brothel-mistress in the "Nighttown" sequence, and has a large and mannish appearance. She has a son in an Oxford college.^[6][10]
• Private Compton is a British soldier who wanders around Nighttown with Private Carr, eventually encountering Stephen Dedalus. At Compton's urging, Carr eventually assaults Dedalus.
• Father John Conmee, a Jesuit priest.
• Punch Costello is a medical student who we first encounter singing a bawdy song in the National Maternity Hospital. He is told by nurse Quigley to be quiet.

• Myles Crawford is the Editor of the Evening Telegraph, and refuses to honour an agreement entered into with Leopold Bloom and Alexander Keyes regarding an advertisement for the "House of Keyes".
• Martin Cunningham is a friend of Leopold and accompanies him in the carriage to Paddy Dignam's funeral and thereafter to Kiernan's pub. There he kindly facilitates Bloom's escape from the Citizen, and to visit Dignam's widow.
• Garrett Deasy is the headmaster in the school where Stephen Dedalus teaches and is pompous and opinionated. He writes a self-important letter to the evening newspaper which Dedalus helps get published, on the subject of foot-and-mouth disease.
• Dilly, Katey, Boody, and Maggy Dedalus are sisters of Stephen Dedalus.
• May Golding Dedalus is the mother of Stephen Dedalus. Stephen, a non-believer, refuses to pray at her deathbed and in consequence, thoughts of May haunt him later in the novel.^[6][10] She states, "I was once the beautiful May Golding" (her maiden name). In the 1967 film of Ulysses, the American director americanizes this as "May Golding Dedalus", an anachronism which does not appear in the book, where European conventions are observed.^{[citation needed]}
• Simon Dedalus is the father of Stephen Dedalus. His character is largely based on Joyce's own father, John Stanislaus Joyce. Simon is a passionate Irish nationalist and supporter of Charles Stewart Parnell, facilitating his financial success within Dublin society in Stephens' earlier years. But with the political "fall from grace" of Parnell, he and his family also fall on hard times. Simon has lost his wife but has continued to maintain an air of respectability within Dublin's "drinking society" where he is known for his wit and singing ability but is unable to provide support for his two daughters. His and Stephen's paths cross several times during the course of the book but the two never meet. Simon briefly mentions concern for Stephen, who is now living on his own and supporting himself, but Stephen feels only the need to escape what remains of his disintegrating family. The novel presents Bloom as Stephen's metaphoric and symbolic father.
• Patrick "Paddy" Dignam – Leopold Bloom attends his funeral from the family home to Glasnevin Cemetery in the chapter Hades. He is survived by Mrs. Dignam and their son Patrick Aloysius "Patsy" Dignam. The Dignams live at number 9, Newbridge Avenue, Sandymount. As he dies in a drunken stupor, he is considered Joyce's analog of Elpenor, who died in similar circumstances and who greeted his friend Odysseus.
• Mrs. Dignam, and Patrick Dignam, Jr.
• Dr. Dixon
• Ben Dollard
• Bob Doran is a drunk in Kiernan's pub and together with The Citizen creates an unpleasant atmosphere for Leopold Bloom ultimately resulting in The Citizen throwing a biscuit tin at Bloom.
