Alfredo Casero (born 12 November 1962) is an Argentine musician, actor and comedian.

The song became a huge hit in Argentina, where it was chosen as the anthem for the national football team to represent the country at the 2002 FIFA World Cup, in South Korea and Japan.

In 2004 Casero played the character 'Roque Rizzutti' in the Argentine soap Locas de amor.

He was featured, along with Japanese rock band The Boom (authors of Shima Uta) and Japanese-Argentine folk singer Claudia Oshiro on the Japanese New Year's Eve television show, Kōhaku Uta Gassen, in its 53rd edition (New Year's Eve, December 2002).

Since then he's been devoted to the "Casero Experimendo", an experiment of blogging/humour and theater presentations, all made around improvisation.
