The 1948 Monaco Grand Prix was a Grand Prix motor race, held in Monte Carlo on 16 May 1948.[2]
The first event under a new formula, 1½ litres supercharged or 4½ litres naturally aspirated, it featured a motley crowd of marques.[3] Jean-Pierre Wimille's 1430cc Simca-Gordini took an early lead, but was overwhelmed by the Maserati 4CLs of Giuseppe Farina and then Luigi Villoresi.[4] Farina would take the win.
The event included a motorcycle race, open to 500cc bikes, for the only time in the Monaco Grand Prix's history.[5] It was marred by the death of British rider Norman Linnecar.[6]
