Zachary Zorn (born March 10, 1947) is an American former competition swimmer for the University of California Los Angeles and a 1968 Olympic gold medalist in the 4x100-meter freestyle relay.

[3] As a high performing swimmer for Buena Park, Zorn signed to swim for the University of California Los Angeles in May 1965.

[4] In 1968, he won the 100-meter freestyle NCAA title competing for University of California, Los Angeles under exceptional Coach Bob Horn.

[1] At the Santa Clara Invitational, an International Meet in July 1968, he won the 100-meter event in 53.8, beating out Yale swimmer and 1964 Gold medalist Don Schollander.

As he had previously set the individual world record in the 100-meter event at the Olympic trials, his last place finish was a disappointment and Australian teenager Michael Wenden's gold medal in the even was considered unexpected.
