James Byron Dean (February 8, 1931 – September 30, 1955) was an American actor. He is remembered as a cultural icon of teenage disillusionment and social estrangement, as expressed in the title of his most celebrated film, Rebel Without a Cause (1955), in which he starred as troubled teenager Jim Stark. The other two roles that defined his stardom were loner Cal Trask in East of Eden (1955) and surly ranch hand Jett Rink in Giant (1956).

In recognition of his performance in East of Eden, Dean was nominated posthumously for the 1956 Academy Awards as Best Actor in a Leading Role of 1955, the first official posthumous acting nomination in Academy Awards history.

Dean received his second posthumous Best Actor Academy Award nomination for his role in Giant at the 29th Academy Awards in 1957 for films released in 1956.
