Jerome Alan Heidenreich (February 4, 1950 – April 18, 2002) was an American competition swimmer for Southern Methodist University, a 1972 Munich Olympic champion, and a former world record-holder.

The final time in the U.S. gold medal winning 4x100 freestyle relay was a World Record 3:26.42, with Mark Spitz swimming the anchor leg, and the Soviet Union finishing second.

The relay was the final swimming event of the Olympics, and was met with considerable celebration as Spitz received his seventh gold medal as a result of the U.S.

He later coached Master's Swimming at Ken Cooper Aerobics Center in Dallas.

On April 18, 2002, he killed himself with an overdose of prescription medicine at his home in Paris, Texas.
