Lytton's Diary is a 1985–86 British comedy-drama programme created and written by Peter Bowles and Philip Broadley. Produced by Thames Television for ITV, it originated as a single play on the anthology programme Storyboard before expanding into two popular series, known for their mix of glamour, intrigue, and social commentary.

Bowles stars as Neville Lytton, a suave and successful Fleet Street gossip columnist for the Daily News. Lytton navigates the world of high-society scandals, political corruption, and personal challenges, balancing his professional life with his love life and his ambition to write a novel.
