Phillip Ferdinand Mahre (born May 10, 1957) is a former World Cup alpine ski racer, widely regarded as one of the greatest American skiers of all time.

His total of 27 World Cup race wins is fourth among Americans, only behind Mikaela Shiffrin, Lindsey Vonn, and Bode Miller.

The Mahre twins worked extensively with the company throughout their careers, developing custom race skis ideally suited to their needs.

He made his first podium in March with a second in a giant slalom at Copper Mountain, Colorado,[8] and finished the 1976 World Cup season in 14th place in the overall standings.

In 1978 he placed second in the overall standings, followed by third in 1979, despite breaking his lower left tibia in early March at the pre-Olympic giant slalom at Whiteface near Lake Placid.

Steve skied down last, needing only a solid run to take the gold, but a series of mistakes dropped him into second place, and Phil became the Olympic champion.

Portland's Bill Johnson (downhill) and Seattle's Debbie Armstrong also won gold, and Christin Cooper of Sun Valley took the silver for an American 1–2 finish in the women's giant slalom.

The Mahre twins raced a limited World Cup schedule during the 1984 season, and retired from the circuit in early March at age 26.

In 1985, Phil and his brother released their book No Hill Too Fast, which chronicles their childhood and World Cup careers and includes a series of instructional sections titled "How to Ski the Mahre Way".

That same year the twins established the Mahre Training Center in Keystone, Colorado, and continue to run it to this day in Deer Valley, Utah.
