Dennis Neilson-Terry (21 October 1895 – 14 July 1932) was a British actor, theatre manager and producer, who starred in a number of films between 1917 and 1932.
He was the son of the actor Fred Terry and his wife, the actress Julia Neilson. In his early years he had been seen as a rising Shakespearean. After the First World War he specialised, as his parents had done before him, in less demanding roles in ephemeral but popular and profitable plays. While touring in southern Africa with such a repertory he contracted pneumonia and died at the age of 36.
