The 2023 Prix de l'Arc de Triomphe was a horse race held at Longchamp Racecourse on Sunday 1 October 2023. It was the 102nd running of the Prix de l'Arc de Triomphe. The race was won by Serge Stempniak and Gousserie Racing's three-year-old colt Ace Impact, trained in France by Jean-Claude Rouget and ridden by Cristian Demuro. It was a second win in the race for Rouget and Demuro, who had previously won the 2020 Arc with Sottsass. Ace Impact became the first French-trained three-year-old colt to win the Arc since Rail Link in 2006.

Ace Impact defeated Westover by one and three-quarter lengths, with Onesto finishing third and Through Seven Seas fourth. Sent off as the 5/2 favourite, Ace Impact remained unbeaten after six starts and won the Arc on his first attempt over 2,400 metres.

The race was run on good to soft ground and attracted 15 runners. Ace Impact was held towards the rear of the field before making his move around the final turn. He produced a strong acceleration in the straight to pass his rivals and win decisively.
