John Emery (May 20, 1905 – November 16, 1964) was an American stage, film, radio and television actor. Born in New York City, he was the son of stage actors Edward Emery (c. 1861 – 1938) and Isabel Waldron (1871–1950). He was educated at Long Island's La Salle Military Academy.
Through the late 1930s to the early 1960s, he appeared in small roles in many Hollywood films, beginning with James Whale's The Road Back (1937). He was also known for his television work, appearing on programs like I Love Lucy and Have Gun Will Travel. In 1946 he starred in a radio program, playing the title character, detective Philo Vance.
The only husband of Tallulah Bankhead, the two married on August 31, 1937 in Jasper, Alabama and were divorced on June 13, 1941 in Reno, Nevada. The two remained friendly after their marriage, with Emery later marrying dancer Tamara Geva. Due to their resemblance, Emery was often rumored to be the illegitimate child of John Barrymore. Emery died on November 16, 1964 in New York City, aged 59.
From 1961 to 1964, Emery was romantically involved with actress Joan Bennett, who cared for him during his final illness.
