The 1988 Canadian Grand Prix was a Formula One motor race held on 12 June 1988 at the Circuit Gilles Villeneuve, Montreal. It was the fifth race of the 1988 Formula One World Championship. The 69-lap race was won from pole position by Brazilian driver Ayrton Senna, driving a McLaren-Honda, with French teammate Alain Prost second and Belgian Thierry Boutsen third in a Benetton-Ford.

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.
