True Believer (also released as Fighting Justice) is a 1989 American courtroom drama directed by Joseph Ruben, written by Wesley Strick, and starring James Woods, Robert Downey Jr., Yuji Okumoto, Margaret Colin, and Kurtwood Smith.

The film is loosely based on an investigative series of articles written by Pulitzer Prize-nominated journalist K. W. Lee on the wrongful conviction of immigrant Chol Soo Lee for a 1973 San Francisco Chinatown gangland murder. The news coverage led to a new trial, eventual acquittal and release of the prisoner from San Quentin's Death Row. Strick based the character of Eddie Dodd on real-life Bay Area defense attorney Tony Serra.
