Grace Clawson (15 November 1887 – 28 May 2002), was an English-American supercentenarian who was the oldest living person in the United States and the World's Oldest Person (WOP) for two months in 2002, following the death of fellow American Maud Farris-Luse. She was not recognized as the WOP back then because her age was only posthumously verified by the Gerontology Research Group (GRG) and because Kamato Hongo's age claim was accepted until 2012, when the GRG withdrew its acceptance of it.
She was born in London, England, but her family moved to Montreal, Quebec, Canada, with her only sister. After her parents divorced when she was a teenager, she lived with foster parents until she married Ray Clawson, in 1917. She had two daughters, Viola and Gladys, and became widowed in 1950. Before retiring, she worked as an embroiderer and as an office worker.
