Mavis Hutchison (born 25 November 1924) is a South African athlete. Her career began as a race walker, and her first record was in the 50-mile walk known as the Rand Daily Mail Big Walk in 1963 (9 hours 35 minutes). That same year she was timed over the standard marathon distance of 42.2 km, but took about ten minutes longer than Violet Piercy had done in 1926, and 13 minutes longer than Merry Lepper's time a few months later. Since 2005 she has set South African W80+ master records for 100 metres (18.84 sec), 200 metres (45.46 sec), 400 metres (1:52.88 min), and 800 metres (4:34.13 min).
