Samuel "Sammy" Lee (August 1, 1920 – December 2, 2016) was an American physician and diver. He was the first Asian American man to win an Olympic gold medal for the United States (the second Asian American to win a gold medal overall) and the first man to win back-to-back gold medals in Olympic platform diving.

Lee was born in Fresno, California, to parents of Korean descent who owned what he described as "a little chop suey restaurant". His father was fluent in English and Korean, tutored in French, graduated with a degree in civil engineering from Occidental College, and opened a chop suey restaurant and market. As a twelve-year-old living near Los Angeles in 1932, Lee saw and was motivated by the many Olympics banners and souvenirs on display for the Summer Olympics being held in Los Angeles that year. Later that summer, he found that he could do somersaults much better than all of his friends, which led to his goal of becoming an Olympic champion in diving.

Lee's parents moved to Highland Park, a neighborhood of Los Angeles. At the time, however, Latinos, Asians and African-Americans were only allowed to use the nearby Brookside Park Plunge in Pasadena on Wednesdays, on what was called "international day,” the day before the pool was scheduled to be drained and refilled with clean water. Because Lee needed a place to practice and could not regularly use the public pool, his coach dug a pit in his backyard and filled it with sand. Lee practiced by jumping into the pit.

Lee attended Franklin High School and later was a student-athlete at Occidental, where he received his undergraduate degree before attending the University of Southern California School of Medicine, where he received his M.D. in 1947. He joined the Army Reserve to pay for his medical school tuition.

In 1996 Lee was interviewed by Huell Howser in California's Gold Episode 702. During the interview, he explained how he worked as a locker boy at the Los Angeles Swimming Stadium at the same time Esther Williams worked as a locker girl.

Under the tutelage of renowned diving coach Jim Ryan, Lee won the United States National Diving Championships in 1942 in both the 3-meter springboard and the 10-meter platform events, becoming the first person of color to capture the United States national championship in diving. In 1946, he again triumphed at the 10-meter platform event while finishing third at the 3-meter springboard competition at the national diving competition in San Diego.

At the 1948 Summer Olympics in London, England, Lee earned a bronze medal in the 3-meter springboard and a gold medal in 10-meter platform diving events. In so doing, he became the second Asian American to earn a gold medal, behind only Vicki Draves, who won an Olympic gold medal two days earlier in springboard diving.

Four years later, by then a major in the United States Army Medical Corps, he expected to serve in the Korean War, but he was instead sent to compete in the Olympic Games ("but you better win", he was told). He won the gold medal in the 10-meter platform competition at the Olympics in Helsinki, Finland.
