Florence Beatrice Paton (née Widdowson; 1 June 1891 – 12 October 1976) was a Labour Party politician in the United Kingdom, and a Member of Parliament (MP) from 1945 to 1950.
A Methodist lay preacher, she was initially a Liberal, but joined the Independent Labour Party (ILP) in 1917.
Under her maiden name of Florence Widdowson, she first stood for Parliament at the Cheltenham by-election in 1928, and at the 1929 general election, she contested the Rushcliffe constituency in Nottinghamshire.
After her marriage in 1930 to the future Labour MP John Paton, she stood again in Rushcliffe in 1931.
During a supply day debate on Scottish civil aviation estimates on 31 May 1948, she became the first woman to preside over the whole House of Commons.
