Porgy: A Play in Four Acts is a play by Dorothy Heyward and DuBose Heyward, adapted from the short novel by DuBose Heyward. It was first produced by the Theatre Guild and presented October 10, 1927 – August 1928 at the Guild Theatre in New York City. Featuring a cast of African Americans at the insistence of its authors—a decision unusual for its time—the original production starred Frank Wilson, Evelyn Ellis, Jack Carter, and Rose McClendon. Porgy marked the Broadway directing debut of Rouben Mamoulian. The play ran a total of 55 weeks in New York, and the original cast toured the United States twice and performed for 11 consecutive weeks in London.

Dorothy Heyward was an American playwright.
