Estadio San Martín de Porres is a multi-purpose stadium in Lima, Peru. It is currently used by the football club Sporting Cristal. The stadium's maximum capacity is 20,000, however the southern stand is not opened because it borders the Rimac River making its capacity 18,000.
The stadium was built in the 1960s and Sporting Cristal did not use it often in the following decades. It would be used by second division teams and district teams of San Martín de Porres. In 1995, Sporting Cristal rented the stadium from the Instituto Peruano del Deporte and renovated the stadium. On September 24, 1995, Cristal used the stadium to play against Cienciano and won 6-0. From that point on, the stadium is used by Cristal as its home ground except against Alianza Lima and Universitario de Deportes. For these high-risk games, Cristal move their home games to the Estadio Nacional. Another first division club that uses this stadium is Universidad San Martín de Porres.
