Circuit de Monaco is a street circuit laid out on the city streets of Monte Carlo and La Condamine around the harbour of the principality of Monaco. It is sometimes referred to as "Monte Carlo" because it is largely inside the Monte Carlo neighbourhood of Monaco.

The idea for a Grand Prix race around the streets of Monaco came from Antony Noghès, the president of the Monegasque car club and close friend of the ruling Grimaldi family. The inaugural race was held in 1929 and was won by William Grover-Williams in a Bugatti.
