Hautacam is a ski resort in the French Pyrenees. It is situated in the Hautes-Pyrénées department, in the Occitania region. In road bicycle racing, the ascent to Hautacam is known as a tough climb, which is used occasionally in the Tour de France.

Starting from Argelès-Gazost, the climb is 17.3 km (10.7 mi) long. Over this distance, the climb gains 1,170 m (3,840 ft) in altitude to the top of the climb at 1,635 m (5,364 ft), at an average gradient of 6.8%.

The stage finishes of the Tour de France in 2008 and 2014 were at an altitude of 1,520 m (4,990 ft) and in previous races were at 1,560 m (5,120 ft). The climb used by the Tour de France starts at Ayros-Arbouix, from where there is 13.6 km (8.5 mi) to the finish, climbing 1,164 m (3,819 ft), at an average gradient of 7.8%.

Hautacam first held a Tour de France stage in 1994, won by Luc Leblanc. Since then, it has been used a further five times, including the final mountain stage of the 2014 race.

During the 1996 Tour de France the reign of five time champion Miguel Indurain effectively came to an end when Bjarne Riis launched an attack on Hautacam, claiming the stage victory and putting himself in position to win the Tour which he eventually would.

It was on the climb to Hautacam that Lance Armstrong set up his victory in the 2000 Tour de France, until being disqualified for doping. In appalling weather, the race arrived at the first mountain stage, with Javier Otxoa the only survivor from an early break. On the final climb, Armstrong went off alone into the wind and rain leaving his challengers struggling, pushing Jan Ullrich into second place by four minutes. Once Armstrong had taken the Maillot Jaune, he was never seriously challenged until the end of the race.
