Jon Culshaw (born 2 June 1968[1]) is an impressionist who has played multiple roles for Big Finish Productions.

Most notably, Culshaw has voiced the Brigadier and Kamelion, both originally played by actors who had by then passed away. In various productions, he played Brigadier Lethbridge-Stewart alongside Tim Treloar as the Third Doctor, Katy Manning as Jo Grant, and Jemma Redgrave as Kate Stewart. Before doing so for Big Finish, Culshaw had impersonated Nicholas Courtney's Brigadier in multiple Target novelisation audiobooks.

He is a member of the Dead Ringers comedy troupe, which feature a number of Doctor Who parody sketches.

Culshaw is renowned for his ability to impersonate the voice of Tom Baker as the Fourth Doctor, a role in which he has made numerous sketch appearances as well as prank telephone calls for Dead Ringers. Among the recipients of Culshaw's prank calls from "the Doctor" were Doctor Who actors Sylvester McCoy, Colin Baker, Peter Davison, and Tom Baker himself. In full makeup as Tom Baker, Culshaw interviewed the real Tom Baker, who had no problem with this imitation at all.

He performed the role of Tom Baker's voicemail in The Five(ish) Doctors Reboot.

He was an audience member for The Science of Doctor Who and also contributed to the charity reference book Behind the Sofa: Celebrity Memories of Doctor Who.
