Dorothy Sebastian (April 26, 1903 – April 8, 1957) was an American film and stage actress.

Sebastian was born and raised in Birmingham, Alabama. In her youth, she aspired to be a dancer and a film actress. Her family frowned on both ambitions, however, so she fled to New York at the age of 15. Upon her arrival in New York City, Sebastian's southern drawl was thick enough to "cut with a knife". She followed around theatrical agents before returning at night to a $12-a-month room, after being consistently rejected.

Sebastian's first contact in Hollywood was Robert Kane, who gave her a film test at United Studios. She performed in George White's Scandals and later co-starred with Joan Crawford and Anita Page for a popular series of MGM romantic dramas including Our Dancing Daughters (1928) and Our Blushing Brides (1930). Sebastian also appeared in 1929's Spite Marriage, wherein she was cast opposite her then-lover Buster Keaton.

By the mid-1930s, Sebastian was semi-retired from acting after marrying Hopalong Cassidy star William Boyd. After their 1936 divorce, she returned to acting appearing in mostly bit parts. Her last onscreen appearance was in the 1948 film The Miracle of the Bells.

Sebastian married actor William Boyd in December 1930 in Las Vegas, Nevada. They began a relationship after meeting on the set of His First Command in 1929. They divorced in 1936.

In 1947, Sebastian married Miami Beach businessman Harold Shapiro to whom she remained married until her death.

On April 8, 1957, Sebastian died of cancer at the Motion Picture & Television Country House and Hospital in Woodland Hills, California. She is buried at Holy Cross Cemetery in Culver City, California.

For her contribution to the motion picture industry, Dorothy Sebastian has a star on the Hollywood Walk of Fame at 6655 Hollywood Blvd.
