Lelei Alofa Fonoimoana also known by her married name Lelei Moore, is an American swimmer who at age 15 she helped set an American record in the 400 medley relay and at age 17 competed in the 1976 Summer Olympics in Montreal, Quebec. She earned a silver medal as a member of the second-place U.S. team in the 4×100-meter medley relay, and finished seventh in the 100-meter butterfly missing a medal by only five-tenths of a second.

At her alma mater, BYU, she amassed a total of 11 All-America awards, nearly double the number earned by any other BYU female athlete. She has held or holds five school records ar sea level - 50, 100, and 200-meter butterfly as well as the 100 and 200-meter individual medley.

In her freshman season, LeLei scored all of BYU's 64 points at the AIAW National Championships. She collected five All-America awards in the butterfly and individual medley events while picking up an 18th-place finish for the team.

As a sophomore, she won three more All-America awards; as a junior, she won two; and then she sat out the 1979-80 collegiate season to practice in Florida for the Olympic trials.

During her senior season, LeLei, a pre-med major, won her eleventh All-America award in her specialty, the 100-meter butterfly. That year she was selected Outstanding Senior Female Athlete by the Cougar Club and was named to the AIAW All-Region Team. Although the conference did not award honors until her junior year, she headed the all-Conference list in her final two seasons.

Since leaving BYU, LeLei has enjoyed extensive professional employment as an assistant swim coach at UCLA, a senior lifeguard, a therapist, and a dance instructor.
