Anita Stewart (born Anna Marie Stewart; February 7, 1895 – May 4, 1961) was an American actress and film producer of the early silent film era. Stewart was born in Brooklyn, New York as Anna Marie Stewarton February 7, 1895. Her two siblings, George and Lucille Lee, also acted in films. Stewart began her acting career in 1911 while still attending Erasmus Hall High School in extra and bit parts for the Vitagraph Corporation of America at their New York City location. Stewart was one of the earliest film actresses to achieve public recognition in the nascent medium of motion pictures and achieved a great deal of acclaim early in her acting career. Among her earlier popular roles were 1911's enormous box office hit adaptation of A Tale of Two Cities, directed by William J.Humphrey, and having an all-star cast including Maurice Costello, Florence Turner, Norma Talmadge and John Bunny, as well as roles in 1913's The Forgotten Latchkey and The White Feather. In 1917, she married Rudolph Cameron and became the sister-in-law of film director and actor Ralph Ince, who began giving the young actress more prominent roles in films for Vitagraph. Throughout the 1910;s and into the early 1920's, Stewart was one of the silent screen's most popular actresses and was often paired in romantic roles with real-life husband, actor Rudolph Cameron. Stewart was also featured opposite such screen legends as Mae Busch and Barbara La Marr. Her two siblings, George and Lucille Lee, also acted in films. 

Stewart left her lucrative Vitagraph Studios career in 1918 to accept a contract with fledgling film mogul Louis B. Mayer by the terms of which she would head her own production company at the Mayer studios in Los Angeles. It was alleged that Stewart was recovering from an illness in a Los Angeles hospital when Mayer convinced her to leave Vitagraph for an undisclosed but exorbitant sum of money. Between 1918 and 1919, Stewart produced seven moderately successful vehicles, starring in all of them. Throughout the 1920's, she continued to be featured in prominent roles in silent films. Following Stewart's divorce from Cameron in 1928, Stewart married George Peabody Converse the following year. Like many of her silent film contemporaries, Stewart found the transition to sound film extremely difficult. After making just one musical short in 1932, The Hollywood Handicap, Stewart retired from the screen. Stewart authored the murder mystery novel, The Devil's Toy, published in New York in 1935 by E.P. Dutton. Though the book's dust jacket traded on the author's Hollywood connection, the plot concerned the killing of a stage actor and was set in San Francisco. On May 4, 1961, Stewart died of a heart attack in Beverly Hills, California.
