What is Lionel Messi's nickname?

Lionel Messi's nickname is “The Flea,” translated from the Spanish “La Pulga.” The nickname refers to Messi's small stature and his remarkably quick, elusive movement on the soccer field.

Messi was unusually short as a child and was diagnosed with growth hormone deficiency. At age 13, he moved from Argentina to Spain to join Barcelona's youth academy, La Masia, where the club helped cover his medical treatment. His low center of gravity later became a major advantage, helping him change direction rapidly while keeping close control of the ball.

Spanish-language broadcasters and fans often use “La Pulga,” while “La Pulga Atómica,” or “The Atomic Flea,” is another famous variation. The nickname is not an official title and does not replace his name, but “The Flea” is the standard English answer in trivia. Messi is also commonly called “Leo” and “La Pulga Atómica,” which explains why the shorter form can sometimes appear alongside several other nicknames.
