San Isidro (Lima 27) is a district of the Lima Province in Peru, and one of the upscale districts that comprise the city of Lima.

Officially established on April 24, 1930, San Isidro has become a major financial quarter in recent years, as many banks and businesses left downtown Lima to set up their headquarters in modern office blocks.

The district has a total land area of 9.78 km². Its administrative center is located at 109 meters above sea level.

For more than fifty years, the border at the western area of the district has been disputed with neighboring Magdalena del Mar. A judge ordered the councils of both districts to deposit the money of the affected areas' taxpayers in the National Bank of Peru until this long-standing conflict is resolved.

According to a 2002 estimate by the INEI, the district has 68,438 inhabitants and a population density of 6,165.6 persons/km². In 1999, there were 20,598 households in the district.

San Isidro prides itself on being home to many Peruvian artists. A few museums, as well as the Huaca Huallamarca, a pre-Inca burying temple which dates back to the 4th century where concerts and exhibitions are held occasionally, show the cultural heritage of the district.

Peru ⁱ/pəˈruː/ (Spanish: Perú; Quechua: Perú;Aymara: Piruw), officially the Republic of Peru (Spanish: República del Perú, pronounced: [reˈpuβlika ðel peˈɾu] ( listen)), is a country in western South America. It is bordered on the north by Ecuador and Colombia, on the east by Brazil, on the southeast by Bolivia, on the south by Chile, and on the west by the Pacific Ocean.

Peruvian territory was home to ancient cultures, spanning from the Norte Chico civilization, one of the oldest in the world, to the Inca Empire, the largest state in Pre-Columbian America. The Spanish Empire conquered the region in the 16th century and established a Viceroyalty, which included most of its South American colonies. After achieving independence in 1821, Peru has undergone periods of political unrest and fiscal crisis as well as periods of stability and economic upswing.

Peru is a representative democratic republic divided into 25 regions. Its geography varies from the arid plains of the Pacific coast to the peaks of the Andes Mountains and the tropical forests of the Amazon Basin. It is a developing country with a high Human Development Index score and a poverty level around 31%. Its main economic activities include agriculture, fishing, mining, and manufacturing of products such as textiles.

Isidro and Ysidro are Spanish forms of the personal name Isidore. San Isidro or San Ysidro may refer to:
