Marjorie Gestring was a competitive springboard diver from the United States. At the age of 13 years and 268 days, she won the gold medal in 3-meter springboard diving at the 1936 Summer Olympics in Berlin, making her at the time the youngest person ever to win an Olympic gold medal. She remains the second-youngest Olympic gold medalist, as of 2024. A multi-time national diving champion in the United States, she was given a second Olympic gold medal by the United States Olympic Committee after the 1940 Summer Olympics were called off due to the advent of World War II. Gestring attempted to return to the Olympics at the 1948 Games, but failed to qualify for the US team. She has been inducted into the International Swimming Hall of Fame and the Stanford Athletic Hall of Fame.

The 1936 Summer Olympics, officially known as the Games of the XI Olympiad and commonly known as Berlin 1936, was an international multi-sport event held from 1 to 16 August 1936 in Berlin, Germany. Berlin won the bid to host the Games over Barcelona at the 29th IOC Session on 26 April 1931. The 1936 Games marked the second and most recent time the International Olympic Committee gathered to vote in a city that was bidding to host those Games. Later rule modifications forbade cities hosting the bid vote from being awarded the games.
