Bajos de Mena, Urban district in Puente Alto, Santiago, Chile

Bajos de Mena is a densely residential district in the southwestern part of Santiago, characterized by numerous apartment complexes and family homes. The area also includes green spaces and has been equipped with new infrastructure such as parks in recent years.

The land originally belonged to the Mena family before being transferred to the Catholic Church in 1886. During the 1990s, the area was developed into a residential zone to meet growing housing demand.

The name comes from the Mena family, who owned land on the north bank of the Maipo River. The cemetery founded on their former grounds in 1903 admitted all religions, and surrounding communes buried their dead there at a rate of 10 to 15 graves a day. The Russian Orthodox Cemetery of Puente Alto opened nearby in 1955.

Bajos de Mena lies about 5 km from the Plaza de Puente Alto, where the nearest banks are; pharmacies are roughly a kilometre away. The 66th Carabineros station opened in 2017, and the Eighth Fire Company of Puente Alto also serves the sector. A Metro Line 9 extension to the sector was announced in 2018.

Juan Pablo II Park opened in 2013 on the site of the illegal landfill known as La Cañamera. The sector's cemetery, opened in 1903 on land Manuel Mena gave to the Catholic Church, accepted burials from all faiths, and in 1955 the Russian Orthodox Cemetery of Puente Alto was inaugurated nearby.
