Royston Albert Fransen (born 4 January 1916 in Tottenham, north London, England; died 5 July 1985) was a British high diver and stuntman.
Fransen's professional high and fire diving career lasted over 40 years until an accident during a 1985 performance led to his death.
As a youth and during the 1930s, Fransen practiced dry and without water at home in suburban Pinner, to improve his athletic hobby and sporting skills.
In the late 1940s together with his elder brothers and friends, including diver-stuntman George Baines and diver Vera Beaumont, Fransen created a high dive stunt and show, aiming to generate an income.
Circus and trade fairs throughout the capital cities of the world were regularly visited, and his act appeared on television across Europe.
