Peter Pratt (21 March 1923 – 11 January 1995) was an English actor and singer. He was best known for his comic roles in the Gilbert and Sullivan comic operas.

After leaving the company, he moved on to a career in theatre, television, concert and radio, although he continued to perform the Gilbert and Sullivan roles throughout his career. Among his television roles Pratt was the second actor to play the Master in the science fiction series Doctor Who.
