Thomas Baptiste (1929-2018) was a Guyanese-born British actor and opera singer.

Baptiste moved to Britain in the late 1940s and studied music which led to him gaining scholarships to the National School of Opera and the Royal Academy of Music.

Baptiste's role in Noel Coward's Nude with Violin with John Gielgud, Patience Collier and Kathleen Harrison in 1956, signalled a shift away from music and towards acting. Baptiste was known for his role as Riley in the first professional production of Harold Pinter's The Room in 1960, and in 1963 he played the first Black character to appear in Coronation Street, a bus conductor who was falsely sacked as a result of a racist altercation with Len Fairclough.

In the 1960s, Baptiste co-founded an advisory committee of the British Actors' Equity Association, to represent Black actors in Britain.
