The 1988 FIA Formula One World Championship was the 42nd season of FIA Formula One motor racing. It featured the 1988 Formula One World Championship for Drivers and the 1988 Formula One World Championship for Constructors, which were contested concurrently over a sixteen-race series that commenced on 3 April and ended on 13 November. The World Championship for Drivers was won by Ayrton Senna, and the World Championship for Constructors by McLaren-Honda. Senna and McLaren teammate Alain Prost won fifteen of the sixteen races between them; the only race neither driver won was the Italian Grand Prix, where Ferrari's Gerhard Berger took an emotional victory four weeks after the death of team founder Enzo Ferrari. McLaren's win tally has only been bettered or equalled in seasons with more than sixteen races; their Constructors' Championship tally of 199 points, more than three times that of any other constructor, was also a record until 2002.

Formula One, commonly known as Formula 1 or F1, is the highest class of international racing for open-wheel single-seater formula racing cars sanctioned by the Fédération Internationale de l'Automobile (FIA). The FIA Formula One World Championship has been one of the world's premier forms of racing since its inaugural running in 1950. The word formula in the name refers to the set of rules all participants' cars must follow. A Formula One season consists of a series of races, known as Grands Prix. Grands Prix take place in multiple countries and continents on either purpose-built circuits or closed public roads.
