French skier and auto racer who won a double championship in the downhill and combined events of Alpine skiing during the 1948 Winter Olympics in St. Moritz, Switzerland. His downhill medal came at the debut of the event at the Winter Olympics.

Oreiller was a member of the French Resistance during World War II before joining the great French ski team that dominated Olympic events in the years after the war. A self-assured, clownish personality, he boasted that he was so confident he would win that other skiers should not attempt to compete against him. He made good his boast, taking gold medals in the downhill and Alpine combined skiing events and a bronze medal in the slalom at the 1948 Winter Olympics. Known for his acrobatic style, he would fly over bumps recklessly, then regain his balance in midair. After the Olympics he entered other contests, sweeping all the skiing events at the Harriman Cup of 1949.

In later years he turned to auto sports, winning a French national championship in the tourism category. He died in an accident at the Linas-Montlhéry autodrome in 1962. His memory is still honoured in France, with streets and buildings named for him, including the Henri Oreiller Conference Centre in the ski-resort town of Tignes.
