Charles Rann Kennedy (born Derby, England, 14 February 1871; died Los Angeles, California, 16 February 1950) was an Anglo-American dramatist.

He began life as an office boy, largely educated himself and began lecturing and writing early. He later became an actor, press agent, and theatrical business manager. This led to the production of dramas for the stage with which he combined the writing of short stories, critical articles and poems. He taught for several years at Bennett Junior College in Millbrook, New York. He retired in Los Angeles.

After 1905, he spent most of his time writing drama, including:

• The Servant in the House, his first success (1908)
• The Winter Feast (1908)
• The Terrible Meek (1911)
• The Necessary Evil (1913)
• The Idol-Breaker (1914)
• The Rib of the Man (1916)
• The Army with Banners (1917)

All of these dramas deal with problems of society and are of a serious, reforming tendency.

• World Within: A Cycle of Sonnets (1956) -- posthumously published collection of sonnets

In 1898, he married actress Edith Wynne Matthison. She was an advisor during the development of his dramas, acted in them, and also taught at Bennett Junior College.
