Carl Ludwig "Luz" Long was a German Olympic long jumper, notable for achieving the silver medal in the event at the 1936 Summer Olympics in Berlin and for his association with Jesse Owens, who went on to win the gold medal for the long jump. Luz Long won the German long jump championship six times in 1933, 1934, 1936, 1937, 1938, and 1939.

The long jump is a track and field event in which athletes combine speed, strength and agility in an attempt to leap as far as possible from a takeoff point. Along with the triple jump, the two events that measure jumping for distance as a group are referred to as the "horizontal jumps". This event has a history in the ancient Olympic Games and has been a modern Olympic event for men since the first Olympics in 1896 and for women since 1948.
