Monte Carlo (French: Monte-Carlo, Occitan: Montcarles, Monégasque: Monte-Carlu) is an administrative area of the Principality of Monaco.

Monte Carlo is widely known for its casino and its prominence. The permanent population is about 15,000 in Quarter. Monte Carlo quarter includes not only Monte Carlo proper where the Le Grand Casino is located, it also includes the neighbourhoods of Saint-Michel, Saint-Roman/Tenao, and the beach community of Larvotto. It is also one of Monaco's 10 wards, with a population of 3,500. It borders the French town of Beausoleil (sometimes referred to as Monte-Carlo-Supérieur).

The "Monte Carlo" name is of Italian origin, meaning "Mount Charles" named after the Prince Charles III of Monaco during the time of his reign.

Founded in 1866, Monte Carlo has a name of Italian origin meaning "Mount Charles", in honor of the then-reigning prince, Charles III of Monaco. The specific mountain is the escarpment at the foot of the Maritime Alps on which the town stands.

The history of the area and the ruling Grimaldi family, however, dates back centuries. The port of Monaco is first mentioned in historical records as early as 43 BC, when Julius Caesar concentrated his fleet there while waiting in vain for Pompey. In the 12th century, the area fell under the sovereignty of Genoa, which was granted the entire coastline from Porto Venere to Monaco. After much conflict, the Grimaldis regained the rock in 1295, but suffered a significant amount of opposition in the ensuing years. In 1506 the Monegasques, under Lucien, Lord of Monaco, were under siege for some four months by the Genoan army, which had ten times the number of men. Monaco officially received full autonomy in 1524, but experienced difficulty retaining power, and on occasions briefly fell under the domination of Spain, Sardinia, and France.

The Monte-Carlo Masters (as of 2012^[update] sponsored by Rolex) is an annual tennis tournament for male professional players held in Roquebrune-Cap-Martin, France, a commune that borders on Monaco. The event is part of the ATP World Tour Masters 1000 on the Association of Tennis Professionals (ATP) Tour. The tournament is played on clay courts and is held every year in the April-May period.

The Monte Carlo tennis championship was first held in 1897. It became an "Open" event in 1969. Between 1970 and 1989 it was a major tournament of the Grand Prix Tour as part of the Grand Prix Championship Series top tier events, before becoming an ATP Championship Series Single Week tennis event.

Beginning in 2009, Monte Carlo became the only ATP World Tour Masters 1000 tournament to not have a mandatory player commitment. Most of the top players still elect to play the event.

Rafael Nadal has won the title 8 consecutive times between 2005 and 2012, making him the only player in the open era to win 8 consecutive titles at the same tournament.
