Rímac (pronunciation: [ˈri.mak]), known until the 19th century as the neighbourhood of San Lázaro, is a district in the Lima Province, Peru.

Downtown Rímac District has, like its southern counterpart, its eastern and western sides divided by Jirón Trujillo, which connects to Lima District's Jirón de la Unión through the Puente de Piedra, the oldest bridge in the whole city.

Rímac's East side features the Plaza de Acho, the most famous bullfighting arena in South America and one of the most well known in the world.

Looking directly from Ricardo Palma Bridge on downtown Lima district's East side can be seen a large building with the logo of Cristal beer, one of two famous Peruvian brands.

The Cerro San Cristóbal, which is the highest point in the Lima Province, is located in the district.
