Michael Bennett (April 8, 1943 – July 2, 1987) was an American musical theatre director, writer, choreographer, and dancer. He won seven Tony Awards for his choreography and direction of Broadway shows and was nominated for an additional eleven.

Bennett choreographed Promises, Promises; Follies; and Company. In 1976, he won the Tony Award for Best Direction of a Musical and the Tony Award for Best Choreography for the musical A Chorus Line. Bennett, under the aegis of producer Joseph Papp, created A Chorus Line based on a workshop process which he pioneered. He also directed and co-choreographed Dreamgirls with Michael Peters.

Bennett was born Michael DiFiglia in Buffalo, New York, the son of Helen (née Ternoff), a secretary, and Salvatore Joseph DiFiglia, a factory worker. His father was Italian American and his mother was Jewish. He studied dance and choreography in his teens and staged a number of shows in his local high school - Bennett High School in Buffalo, NY - before dropping out to accept the role of Baby John in the US and European tours of West Side Story. He gave himself a new last name when he pursued this life in the arts, taking inspiration from his high school.

Bennett's career as a Broadway dancer began in the 1961 Betty Comden–Adolph Green–Jule Styne musical Subways Are for Sleeping, after which he appeared in Meredith Willson's Here's Love and the short-lived Bajour. In the mid-1960s he was a featured dancer on the NBC pop music series Hullabaloo, where he met fellow dancer Donna McKechnie.

Bennett made his choreographic debut with A Joyful Noise (1966), which lasted only twelve performances, and in 1967 followed it with another failure, Henry, Sweet Henry (based on the 1958 novel The World of Henry Orient, which had been filmed under that title in 1964 with Peter Sellers). Success finally arrived in 1968, when he choreographed the hit musical Promises, Promises on Broadway. With a contemporary pop score by Burt Bacharach and Hal David, a wisecracking book by Neil Simon and Bennett's well-received production numbers, including "Turkey Lurkey Time", the show ran for 1,281 performances. Over the next few years, he earned praise for his work on the straight play Twigs with Sada Thompson and the musical Coco with Katharine Hepburn. These were followed by two Stephen Sondheim productions, Company and Follies, co-directed with Hal Prince.

In 1973, Bennett was asked by producers Joseph Kipness and Larry Kasha to take over the ailing Cy Coleman–Dorothy Fields musical Seesaw. In replacing the director Ed Sherin and choreographer Grover Dale, he asked for absolute control over the production as director and choreographer and received credit as "having written, directed, and choreographed" the show.

Bennett's next project was A Chorus Line. The musical was formed out of twenty hours of taped sessions with Broadway dancers. Bennett was invited to the sessions originally as an observer but soon took charge. He co-choreographed and directed the production, which debuted in July 1975 off-Broadway. It won nine Tony Awards and the 1976 Pulitzer Prize for Drama. He later claimed that the worldwide success of A Chorus Line became a hindrance, as the many international companies of the musical demanded his full-time attention. Bennett would later become a creative consultant for the 1985 film version of the musical but left due to creative differences. He always sought creative control over his projects, but Hollywood producers were unwilling to give him the influence he demanded.

The 2008 feature-length documentary Every Little Step chronicles the casting process of the musical's 2006 revival, with re-created choreography by Bennett's long-time associate Baayork Lee, and, in the course of the film, the saga of the original production is re-told through the use of old film clips and interviews from the original collaborators, including Lee, Bob Avian (who was the show's original co-choreographer with Bennett and the director of the revival), composer Marvin Hamlisch and the original's leading lady, Donna McKechnie.
