The 2006 Monaco Grand Prix was a Formula One motor race held on 28 May 2006 at the Circuit de Monaco. The race was the seventh round of the 2006 Formula One season.

The race was remembered by many people for Michael Schumacher's actions during the closing stages of the qualifying session for the race, where he stopped his car in La Rascasse corner, thus preventing his rival Fernando Alonso from attempting to improve his time. Schumacher maintained that this was an innocent mistake; his actions were deemed deliberate by the race stewards and he was demoted to the back of the grid as punishment for his actions, promoting Alonso from second to pole position. It was also remembered for Schumacher coming back from his penalty during the race to finish fifth on a circuit that is notorious for overtaking being almost impossible.

Fernando Alonso went on to win the race, his first in Monaco. Juan Pablo Montoya came second, scoring his last podium and David Coulthard took full advantage of Jarno Trulli's late hydraulic failure to finish in third, scoring Red Bull Racing's first ever podium finish and also first ever podium for Ferrari as an engine supplier for a customer team.
