The 2025 Monaco Grand Prix was a Formula One motor race held on 25 May 2025, at the Circuit de Monaco. It was the eighth round of the 2025 Formula One World Championship. With the aim of promoting better racing, there was an increase in the number of mandatory pit stops for the event. The Grand Prix saw the implementation of a minimum two-stop strategy, in both wet and dry conditions. The teams were also mandated to use at least three sets of tyres in the race, with a minimum of two different tyre compounds if it was a dry race.

Lando Norris took pole position for the race, which he went on to win, his second of the season, with Charles Leclerc second, and Oscar Piastri third. This was the first McLaren race victory at Monaco since 2008.

Due to the Circuit de Monaco's long-running lack of overtaking opportunities, there was only one overtake, and zero inside the top 10, with Mercedes calculating a car needed a 4.5-second pace advantage over the car in front to have even a 50–50 chance at an overtake. One of the two on-track "passes" occurred courtesy of Mercedes's George Russell's intentionally cutting the Nouvelle Chicane for which he received a drive-through penalty. Several teams, including Williams, Racing Bulls, and Mercedes, gamed the new rule mandating a second pit stop by ordering one driver to hold up the rest of the field so that the other driver ahead of them could race in free air and pit without losing track position. Max Verstappen also attempted to take advantage of the two-stop rule by staying out on old tyres and gambling for a free pit stop. He took the lead after polesitter Lando Norris took his second pit stop, but no free pit stop materialised and Verstappen was forced to pit at the end of the race, dropping him to fourth.

Several drivers criticised the Grand Prix following the race. Williams's Carlos Sainz and Alexander Albon admitted that while they understood they needed to (legally) block other drivers for tactical reasons, they did not like it. Sainz warned that should there be no further rule changes, the tactic of blocking other drivers would increase in Monaco in future years.
