William Goldman (August 12, 1931 – November 15, 2018) was an American novelist, playwright, and screenwriter. He came to prominence in the 1950s as a novelist, before turning to writing for film. He won two Academy Awards for his screenplays, first for the western Butch Cassidy and the Sundance Kid (1969) and again for All the President's Men (1976), about journalists Carl Bernstein and Bob Woodward, who broke the Watergate scandal of President Richard Nixon for the Washington Post. Both films starred Robert Redford.

His other notable works include his thriller novel Marathon Man and comedy-fantasy novel The Princess Bride, both of which Goldman adapted for film.

Author Sean Egan has described Goldman as "one of the late twentieth century’s most popular storytellers."
