Cecil Blount DeMille (August 12, 1881 – January 21, 1959) was an Academy Award-winning American film director. He was renowned for the flamboyance and showmanship of his movies.

DeMille was born in Ashfield, Massachusetts while his parents were vacationing there and grew up in Washington, North Carolina. His father, Henry Churchill DeMille (1853–1893), was a North Carolina-born dramatist and lay reader in the Episcopal Church. His mother, Matilda Beatrice (Samuel) DeMille (1853–1923), was born in England to a Sephardic Jewish family but converted to her husband's faith. DeMille attended Pennsylvania Military College in Chester, Pennsylvania from the age of 15. He had an elder brother, William, and a sister Agnes, who died in childhood. Cecil DeMille's famous niece was named for her. After Henry DeMille's death at age 40, Cecil's mother, Beatrice, ran a well-known boarding school for girls in New Jersey.

DeMille directed dozens of silent films, including Paramount Pictures' first production, The Squaw Man (1914), which was co-directed by Oscar Apfel, before coming into huge popularity during the late 1910s and early 1920s, when he reached the apex of his popularity with such films as Don't Change Your Husband (1919), The Ten Commandments (1923), and The King of Kings (1927). A few of his silent films featured scenes in two-strip Technicolor.
