José Alberto Hernández Rojas (born 6 June 1977 in Chimalhuacán) is a Mexican footballer.
He plays as a midfielder for Cruz Azul Hidalgo.
A versatile player most often used in defensive midfield, he was a part of the Cruz Azul team that reached the final of the Copa Libertadores in 2001.
On the strength of that performance, he earned a call to the Mexico national team upon the first appointment of Javier Aguirre as national coach in June 2001.
Hernández received his only cap in Aguirre's first match, a 1-0 win over the United States on July 1, 2001.
