Hugh Sinclair (19 May 1903 – 29 December 1962) was a British actor born in London, the son of a clergyman. He was educated at Charterhouse School and was a graduate of the Royal Academy of Dramatic Art. His first marriage was to the actress Valerie Taylor. In his book The Stage Struck Me! fellow actor Neville Phillips felt Sinclair always played variations of himself, handsome, debonair, suave and witty and excelled in light comedy. By contrast Phillips felt his wife, who Sinclair often appeared opposite, was a dramatic actress of tremendous power with a magnificent voice.
