Geoffrey Kerr (born Geoffrey Kemble Grinham Keen; 26 January 1895 – 1 July 1971) was a British stage and film actor and writer during the middle of the 20th century.

Geoffrey Kemble Grinham Keen was born on 26 January 1895, in London, the son of character actor and theatrical manager Frederick Kerr and his wife Lucy Houghton Keen, née Dowson. His younger sister was the actor Molly Kerr. He was educated at Charterhouse School, where his father had been a pupil, and was intending to join the Civil Service until he wrote and appeared in a very successful school play and decided on a career in the theatre.^[1]

At the start of World War I, he obtained a commission in the Shropshire Light Infantry,^[1] and saw active service in the trenches. A friend from his theatre days before the war arranged for him to receive training in the Royal Flying Corps but he was wounded when his plane crashed and spent the remainder of the war as an instructor in aerial gunnery with the rank of Captain.^[1][2] In 1920, he travelled to the United States for the first time to appear with his father on Broadway. From that point on for the remainder of the 1920s, he travelled back and forth across the Atlantic quite often, appearing on Broadway in New York City, and making silent films back home in Britain.

On Broadway, as Geoffrey Kerr, he performed in such plays as The Stork (1925) and London Calling, the latter which he wrote. He also directed occasionally, and co-starred with wife June Walker on Broadway in The Bachelor Father (1928). He ended his acting career in 1934, though he did appear in a play on Broadway in 1949–50, to celebrate the silver Broadway anniversary of the two stars Alfred Lunt and Lynn Fontanne.^[3]
