2017 Monaco Grand Prix

The 2017 Monaco Grand Prix (formally known as the Formula 1 Grand Prix de Monaco 2017) was a Formula One motor race held on 28 May 2017 at the Circuit de Monaco, a street circuit that runs through the Principality of Monaco. It was the sixth round of the 2017 FIA Formula One World Championship, the seventy-fifth time that the Monaco Grand Prix has been held, and the sixty-fourth time it has been a round of the Formula One World Championship since the inception of the series in 1950.

Ferrari driver Sebastian Vettel entered the round holding a six-point lead over Lewis Hamilton in the World Drivers' Championship, with Valtteri Bottas being third. In the World Constructors' Championship, Mercedes held an eight-point lead over Ferrari, with Red Bull Racing a further eighty-one points behind in third.

Kimi Räikkönen started the race from pole position, his first since the 2008 French Grand Prix. In doing so, he broke Giancarlo Fisichella's record for the most race starts between pole positions, with one hundred and twenty-nine starts since his last pole. Sebastian Vettel won the race, Ferrari's first win in Monaco since 2001. Räikkönen finished second as this was Ferrari's first 1–2 finish since 2010 German Grand Prix. Daniel Ricciardo finished third. With the result, Vettel extended his Drivers' Championship lead over Lewis Hamilton, while in the World Constructors' Championship, Ferrari reclaimed the points lead from Mercedes.

This was also the 306th and final Grand Prix start for 2009 World Champion Jenson Button, who substituted for Fernando Alonso at McLaren while Alonso competed in the Indianapolis 500 that same day. Button retired from the race after a crash with Sauber's Pascal Wehrlein.

McLaren driver Fernando Alonso missed the race in order to participate in the Indianapolis 500. Alonso became the first active Formula One driver to race at the Indy 500 since Teo Fabi in 1984. Jenson Button replaced Alonso for the race.

Prior to the national anthem, a minute's silence was observed on the grid before the race as a mark of respect to the victims of the Manchester Arena bombing earlier in the week.

Thursday morning's first practice ended with Mercedes' Lewis Hamilton setting the quickest lap with 1:13.425, approximately 0.2 seconds quicker than his championship rival Sebastian Vettel. Max Verstappen was third quickest and Toro Rosso's Daniil Kvyat was the fastest driver not in one of the top three teams, setting the sixth fastest time. In second practice, Vettel was quickest with 1:12.720. Second through fourth were Daniel Ricciardo, Kimi Räikkönen, and Kvyat. The Mercedes team had a disappointing second practice as they finished eighth and tenth, off the pace of their championship rivals Ferrari. The session was stopped part way through for ten minutes due to a crash by Lance Stroll.

Saturday's Free Practice 3 ended with Ferrari's Sebastian Vettel setting the bar at 1:12.395, besting his own time set in FP2 by 0.3 seconds to set a new lap record, whilst nearest rival and teammate Kimi Räikkönen was 0.3 seconds behind with 1:12.740. The session was interrupted 8 minutes in by yellow flags when Esteban Ocon of Force India crashed in the swimming pool section, mimicking an incident Max Verstappen had during the 2016 qualifying session. Free practice eventually resumed with 4 minutes remaining. Daniel Ricciardo had a brake-by-wire failure and ended up retiring from the session, leaving him sixth with 1:13.392. McLaren driver Jenson Button ended the session in twelfth, but incurred a 15-place grid penalty for changing the MGU-H and turbocharger, which would be applied after qualifying.
