Juan Miguel Echevarría Laflé is a Cuban athlete specialising in the long jump. He represented his country at the 2017 World Championships, narrowly missing the final. He later won a gold medal at the 2018 World Indoor Championships with a mark of 8.46 m.

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.
