Elizabeth Lee Heiden Reid (born September 27, 1959) is an American athlete who excelled in speed skating, cross-country skiing, and bicycle racing.

Heiden won a bronze medal in the 3,000 m at the 1980 Winter Olympics in Lake Placid, skating on an ankle injury that had bothered her for some time.

She suffered a broken wrist and a ruptured spleen when she fell to the ground in 1980 after a second-floor porch railing gave way.

On November 16, 2013, she was inducted into the US Bicycling Hall of Fame in the "Modern Road & Track Competitor" category.

Heiden's daughter, Joanne Reid, has been a member of the US biathlon national team since 2015 and was an NCAA champion cross-country skier at the University of Colorado Boulder.

Heiden is one of only two American women to have become world allround champion, the other being Kit Klein in 1936.
