José Francisco "Kikin" Fonseca Guzmán (born 2 October 1979) is a Mexican former professional footballer who played as a striker.

Born in León, Guanajuato, Fonseca made his first division debut with La Piedad in the 2001 Invierno season.

Kikin scored another two goals in a match of the 4th round of the Taça de Portugal between Oliveira do Bairro SC and Benfica that ended 5–0.

After being selected by Hugo Sánchez for the 2007 Gold Cup, Fonseca was dropped from the squad for the 2007 Copa America due to his low performances and being shown the yellow card two consecutive games for un-called for fouls and complaints against refs.

On 7 August 2008, Fonseca was called up to join Ericksson's second list of players, after an almost 1+1⁄2-year drought of not playing with the national team.
