Woman's Hour is a radio magazine programme broadcast on BBC Radio 4 in the United Kingdom.
Created by Norman Collins and originally presented by Alan Ivimey, Woman's Hour was first broadcast on 7 October 1946 on the BBC's Light Programme (now called Radio 2). One name creditted with "virtually creating" the programme was Janet Quigley who was also involved with the birth of the UK radio programme, Today.
The programme was transferred to its current home in 1973. Over the years it has been presented by Joan Griffiths, Violet Carson, Olive Shapley, Jean Metcalfe (1947, 1958), Marjorie Anderson (until 1972), Judith Chalmers (1966–70), Sue MacGregor (1972–87), Jenni Murray (since 1987), Martha Kearney (1998 to March 2007), and Jane Garvey (since 8 October 2007).

On 1 January 2005, the show became Man's Hour for one day only, on which it was presented by Channel 4 News anchor Jon Snow. On 18 July 2010, after 64 years of Woman's Hour, the BBC began broadcasting a full series called Men's Hour on BBC Radio 5, presented by Tim Samuels.
