What is Lionel Messi's full first and last name, including middle name?

Lionel Messi’s full first, middle, and last name in the standard English-language form is Lionel Andrés Messi.

He was born on June 24, 1987, in Rosario, Santa Fe, Argentina. “Lionel” is his first name, while “Andrés” is his middle name. Messi is his paternal surname and the name used publicly throughout his football career. In fuller Spanish-language forms, his maternal family name, Cuccittini, may also appear, but it is not normally included when a quiz asks for his first and last name with middle name.

Messi is widely known by the short form “Leo,” a nickname derived from Lionel. He began playing organized football in Rosario before joining Barcelona’s youth system at age 13. His professional career later included Barcelona, Paris Saint-Germain, and Inter Miami, alongside Argentina’s national team.

A common mix-up is treating “Andrés” as part of the surname or supplying an invented middle name such as Antonio or Alejandro. Another is assuming that “Leo” is his formal first name. The accent in Andrés is also part of the conventional spelling.
