Altadena is an unincorporated area in the County of Los Angeles, California, lying in the San Gabriel Valley along the rich apron of the soaring San Gabriel mountains. It is bounded on the west by the Arroyo Seco and Oak Grove Park; on the east by Eaton Canyon, and on the south by the City of Pasadena.
With the abruptly rising San Gabriel Mountains as backdrop, Altadena’s tree-lined neighborhoods and commercial zones comprise one of oldest and most beautiful communities in the San Gabriel Valley.
A distinct history, diverse population, and independent identity characterize the town, which shares a border, school district, and other cultural resources with Pasadena to the south.
Altadena has remained an unincorporated area within Los Angeles County since founding in 1887, and has a Town Council that is among the Fifth District’s most well developed. The Council’s 16 members are elected as an advisory body that communicates and coordinates residents’ needs with public agencies and to the Supervisor of the Fifth District, its official representative on the Los Angeles County Board of Supervisors.
