The Club Atlético de Hidalgo S.A.D. was a football club based in the city of Pachuca, Mexico. Founded on December 24, 1996, it was one of the few football teams from the state of Hidalgo. It spent numerous seasons in the Third Division of Mexico and is considered one of the founding clubs of the competition. In 2009, the club was involved in a match-fixing scandal and was punished with relegation. From that moment, Grupo Pachuca decided to become the majority shareholder with 80% ownership. It played its home matches at the Estadio Revolución Mexicana, with a capacity of 3,500 spectators.
Identified by its red and black colours, from which it received the nickname "rojinegros" or "diablos", it was one of the most decorated clubs in Hidalgo, reaching the final of the Torneo Invierno 1996 Primera División 'A'. In 1998, the club was sold to Deportivo Toluca, and relocated to Mexico City, changing its identity to Atlético Mexiquense.
They returned to the Third Division in November 2003, but in 2015, they disappeared for the last time.
