Jack Watling (13 January, 1923 in Chingford, Essex – 22 May, 2001 in Chelmsford) was a British actor.

He had a long career in low-key British films, originally in easy-going boyish roles and gung-ho young military officers. Early appearances were in We Dive At Dawn (1943), The Way Ahead (1944) and Meet Mr. Lucifer (1953). In 1955 he appeared in Orson Welles' Mr. Arkadin.

His reputation as an effective and reliable television actor took root in the early 1960s. Between 1964-69 he was Don Henderson, the troubled conscience to tough businessman John Wilder (Patrick Wymark) in The Plane Makers and its sequel The Power Game. He played Professor Travers in the BBC science-fiction television series Doctor Who in the serials The Abominable Snowmen (1967) and The Web of Fear (1968), and reprised the role decades later in the independent Doctor Who spin-off video Downtime (1995).

His final roles were all television ones, in series such as Bergerac and Heartbeat.

Watling was the father of actresses Dilys Watling, Deborah Watling (who played the Second Doctor's companion Victoria Waterfield) and actor Giles Watling.

Father of Dilys Watling, Deborah Watling and Giles Watling.

It was first intended That the character of Prof Travers would be included in Doctor Who: The Invasion, but it was the part was thought too small for a actor of Watling's stature so the character was renamed Watkins and played by Edward Burnham instead.
