Estadio Ingeniero Hilario Sanchez is a football stadium in San Juan, Argentina. It is the home ground of San Martin de San Juan. It has a capacity of 17,000 spectators.
It was renovated in 2007 because San Martin de San Juan was promoted to the first division, and the stadium needed a bigger capacity. The capacity was increased from 11,000 to 17,000, and along with it came a new stand.
