The 2011 Paris–Roubaix was the 109th running of the Paris–Roubaix single-day cycling race, often known as the Hell of the North. It was held on 10 April 2011 over a distance of 258 kilometres (160.3 miles) and was the ninth race of the 2011 UCI World Tour season.
Garmin–Cervélo's Johan Vansummeren claimed victory after making a solo breakaway from a four-man group with 15 kilometres (9.3 miles) remaining, holding on to win by 19 seconds at the velodrome in Roubaix. He also held on to victory, despite riding the final 5 kilometres (3.1 miles) with a flat rear tyre. Second place went to Leopard Trek rider and defending race winner Fabian Cancellara who caught the remaining riders from the breakaway – Maarten Tjallingii of Rabobank, Lars Bak of HTC–Highroad and Grégory Rast of Team RadioShack – and outsprinted them in Roubaix. Tjallingii completed the podium in third.
