The 1930 Monaco Grand Prix was a Grand Prix motor race held at the Circuit de Monaco on 6 April 1930. Frenchman René Dreyfus won the race in a privateer Bugatti, ahead of the works Bugattis of Louis Chiron and Guy Bouriat. The race was somewhat marred by allegations of race-fixing.

The 1930 Grand Prix season continued the malaise that had taken over the sport. Although there was little technical advance more privateer teams were forming, getting some factory support. The AIACR continued to mandate its fuel-regulated Formula Libre rules. Across the Atlantic, the AAA abandoned the AIACR regulations. Their new regulations were derisively called the “Junk Formula” by purists, opening up to their own version of Formula Libre: with modified stock-standard cars of up to 366 cu in (6-litres) with two seats.
