Estadio Monumental U, Football stadium in Ate, Peru.

Estadio Monumental U is a football stadium in Ate, east of Lima, featuring four main stands and capacity for over 80,000 spectators. The complex spreads across a large site with multiple levels housing boxes and visitor areas.

Planned in 1989 as a sports complex for Universitario de Deportes, the stadium had its cornerstone laid on 16 January 1991, and the land was bought on 18 October 1994. It opened on 2 July 2000 with a 2-0 win over Sporting Cristal before 80,208 spectators, replacing the Estadio Teodoro Lolo Fernandez. In 2019 and again in 2025 it hosted the single-match Copa Libertadores final.

The stadium is the home ground of Club Universitario de Deportes, whose supporters are known as cremas after the cream and maroon colours painted on the facade in 2016. In November 2010 seats in the Oriente stand were replaced with white and black ones forming a mosaic of Teodoro Fernández, the club's historic striker; a statue of him was unveiled on 31 May 2021. The presidential box is named after writer Mario Vargas Llosa, a club member and 2010 Nobel laureate.

The pitch sits 18 m below ground level, so from outside only the six floors of luxury boxes are visible; the four stands Norte, Sur, Oriente and Occidente each have their own entrance. The east and west stands are all-seaters, while north and south have standing terraces, and a handicapped zone lies behind the western and eastern stands. The Palco Oficial in the western stand holds about 600 people with a private entrance.

Beyond the main pitch, two additional training grounds sit within the complex, used by teams for preparations. In the evenings, powerful floodlights ensure that matches and shows can take place under clear light.
