Timothy Charles Plunket Whidborne (1927–2021) was a British artist notable for his 1969 portrait of Queen Elizabeth II on horseback as Colonel-in-Chief of the Irish Guards, a regiment in which Whidborne had once been a member.

Born in High Wycombe, Whidborne was educated at Stowe School, where he was a contemporary of George Melly. He served as a lieutenant in the Irish Guards and saw action in Mandatory Palestine. In 1949, he became a pupil of Pietro Annigoni. Whidborne exhibited at the Royal Academy in 1954, and in 1966, The Connoisseur recognized him as a leading mural decorator in England.

In 1983, he was among the artists selected to design alternative stamps for the British definitive series, but his design was not adopted, and the Machin series remained in use for the Queen's lifetime.
