Frederick Charles Hannen Swaffer (1 November 1879 – 16 January 1962) was an English journalist and drama critic. Although his views were left-wing, he worked mostly for right-wing publications, many of them owned by Lord Northcliffe. He was a proponent of spiritualism, and an opponent of capital punishment.
Swaffer was born in Lindfield, Sussex, the eldest of eight children of a Folkestone draper, Henry Joseph Swaffer, and his wife, Kate Eugenie Hannen. He was educated at Stroud Green Grammar School, Kent, and joined a local newspaper in Folkestone as an apprentice reporter. His first published article was a review of a performance by George Grossmith at the local town hall. His reviews were so vituperative that he was banned from the local theatre, the first of many such bans during his career. While at Folkestone he read Robert Blatchford's book of socialist essays, Merrie England, and adopted its left-wing views for the rest of his life.
After further experience in provincial journalism, Swaffer joined The Daily Mail in 1902, and worked for its proprietor Alfred Harmsworth (later Lord Northcliffe) for the next seventeen years. In 1904 Swaffer married Helen Hannah, daughter of John Sitton, a Clapham grocer; they had no children. They remained married until Helen's death in 1956, although he left her at intervals for various mistresses.
Swaffer was editor of Northcliffe's Weekly Dispatch and then helped develop The Daily Mirror, originally a paper for women, into a mass-market title. In 1913, he initiated "Mr Gossip" for The Daily Sketch. He also started "Mr London" for The Daily Graphic, and contributed the "Plays and Players" column to The Sunday Times. He was appointed editor of The People in 1924, but was unsuited to the duties of editing a paper, and held the post for only a few months. In 1926 he became drama critic of The Daily Express and The Sunday Express. He later said that although he enjoyed the company of actors, he disliked having to watch them acting, and he accused Noël Coward and others of being "non-existent talents".
