What is the name of Robert De Niro's character in the film 'Taxi Driver'?

Robert De Niro’s character in Martin Scorsese’s Taxi Driver is Travis Bickle.

Travis Bickle is a former U.S. Marine and Vietnam War veteran who works night shifts as a New York City taxi driver. His insomnia, loneliness, and growing disgust with the city’s violence and exploitation fuel an increasingly unstable worldview.

Written by Paul Schrader and released in 1976, Taxi Driver presents Bickle through diary-like voice-over and subjective imagery. His famous mirror monologue, including “You talkin’ to me?”, captures his isolation and his attempt to invent a tougher identity.

Bickle is sometimes confused with De Niro’s other crime-film characters, including Jimmy Conway in Goodfellas, Tommy DeVito in Goodfellas, and Rupert Pupkin in The King of Comedy. Taxi Driver is also distinct from those films because Bickle is a psychologically troubled antihero rather than a conventional gangster or entertainer.
