The '''land speed record''' ('''LSR''') or '''absolute land speed record''' is the highest [[speed]] achieved by a person using a [[vehicle]] on land. By a 1964 agreement between the [[Fédération Internationale de l'Automobile]] (FIA) and [[Fédération Internationale de Motocyclisme]] (FIM), respective governing bodies for racing in automobiles and motorcycles (two or three wheels), both bodies recognise as the absolute LSR whatever is the highest speed record achieved across any of their various categories.<ref name="times19641212"/> While the three-wheeled [[Spirit of America (automobile)|''Spirit of America'']] set an FIM-validated LSR in 1963, all subsequent LSRs are by vehicles in FIA Category C ("Special Vehicles") in either class JE (jet engine) or class RT (rocket powered).<ref>{{cite web |title=List Of FIA Absolute World Records |url=https://www.fia.com/sites/default/files/basicpage/file/World%20Records.pdf |publisher=FIA |access-date=9 April 2023}}</ref><ref>{{cite web |title=Official List Of World Speed Records Homologated By The FIA In Category C |url=https://www.fia.com/sites/default/files/basicpage/file/Category%20C_0.pdf |publisher=FIA |access-date=9 April 2023}}</ref>
