It is the second most populated district of Lima metropolitan area and Peru.

History
Since 1945, continuous invasions of territory in what was then part of the Carabayllo District, ended up in the creation of the Distrito Obrero Industrial 27 de Octubre on May 22, 1950, which is still celebrated as the district's anniversary.

The district was composed of the following haciendas: Chuquitanta, Pro, Naranjal, Infantas, Santa Rosa, Garagay Alto, G. Bajo, Chavarría, Mulería, Aliaga, Condevilla, San José, Palao, Huerta Sol, Oquendo, San Agustín and Marquez. The last three became part of Callao Province, in 1956.

In 1962, after the canonization of St. Martin de Porras, the name of the district was changed to its current name. Although historians have shown that the saint's actual last name was Porras, the district has retained the original spelling.

The district of Los Olivos was created in 1989, stripping some of San Martín de Porres' northeastern territory.

Borderline conflicts
In 1956, due to the territorial cut due to the expansion of the Constitutional Province of Callao, an area of conflict arose with the Callao District. This dispute arose from the imprecision in the wording of the boundaries and the lack of cartography of the law, in addition to the disappearance of the original stone milestones due to the urbanization process. The conflict or indetermination of limits is still in force, as it corresponds to a district-provincial struggle, and is waiting to be fully defined by the Metropolitan Municipality of Lima, the Regional Government of Callao, the Provincial Municipality of Callao, the Municipality of San Martín de Porres, the Presidency of the Council of Ministers and the Congress of the Republic.

In 1989, due to the territorial reduction due to the creation of the Los Olivos district, two conflict zones arise, one with the Independencia District and the other with the Comas District. These districts argue that, when Los Olivos was created, part of the old industrial zone in San Martín de Porres would correspond to them to be annexed, however, according to San Martín de Porres, the law for the creation of a new district could not detail the transfer of territory to others not involved and because it was not an express request of the residents. It also highlights that the laws creating Comas (Law No. 13757) and Independencia (Law No. 14965, Law No. 16012) mark their limits on the Old Pan-American North (today Avenida Túpac Amaru).The conflict remains and both zones are not yet defined by the Metropolitan Planning Institute, the Metropolitan Municipality of Lima or the Congress of the Republic.

Conflict with Callao district
The area in territorial conflict with the district of Callao has a linear extension of approximately 11 kilometers and is located in two segments between the summit of Cerro Márquez to Cerro La Regla and from the eastern edge of Cerro La Regla to the Rímac River.

The first mentioned segment begins between passing through the summit of Cerro Márquez until entering Cerro La Regla. In this area, since 2000, settlements and urbanizations have been developed such as Floresta de Oquendo, Villas de Oquendo, Costa Azul, Palmeras de Oquendo, among others that are located between Alameda Central and Bertello avenues and archaeological sites such as the Inca Palace of Oquendo.

The second mentioned segment is from the eastern edge of Cerro La Regla moving south, crossing the Rímac River until reaching Colonial Avenue. In this area, since 1980, the El Álamo, Las Fresas, Sesquicentenario, Industrial Bocanegra, Santa Rosa, Bocanegra urbanizations have been developed, among others, which are located between Cuzco and Faucett avenues, close to the Jorge Chávez Airport.

Conflict with Independencia district
The area in territorial conflict with the district of Independencia has a quadrangular shape of 2.40 square kilometers. It is delimited by Panamericana Norte, Naranjal, Tupac Amaru and Tomas Valle avenues, and contains the urbanizations Naranjal, Industrial, Mesa Redonda, Mulería, Industrial El Naranjal, Industria Panamericana Norte and the Residential Naranjal Housing Association. The conflict also affects the municipal tax system since the large shopping centers pay taxes to Independencia, however the urbanizations and small and medium businesses pay taxes in San Martín de Porres.

Conflict with Comas district
The area in territorial conflict with the district of Comas has a triangular shape of 1.28 square kilometers. It is delimited by San Bernardo, Panamericana Norte and Gerardo Unger avenues, up to the next bank of the Chillón River, and contains the urbanizations Santa Luisa, Santa Rosa de Infantas, Pro Industrial IV and IX Sector III Stage; the Municipal Human Settlement No. 02; and the housing associations José de San Martín, José Carlos Mariátegui and San Miguel.
