Maurice Caven was the leader of a band of space pirates in the Doctor Who serial, The Space Pirates.


Caven and his men intended to smuggle away a valuable mineral called argonite that was discovered on the planet Ta. Caven managed to persuade Madeleine Issigri of the Issigri Mining Company to set up a base on Ta where he and his men could obtain the argonite. Later, Caven escaped with his fellow, Dervish, in their ship and escaped into space after some setbacks occurred when the Doctor and his friends arrived. Caven threatened to destroy Ta but his ship was destroyed by the Space Corps.
