Alum Rock ('/æ//l//əm/) is a district of San Jose, California, located in East San Jose. Formerly an independent town, it has been a neighborhood of San Jose since the 1950s, though some portions are still unincorporated as a census designated place. Alum Rock is one of San Jose's most notable and historic Chicano/Mexican American districts. It is home to Alum Rock Park, the oldest municipal park in California and one of the largest in the country.

Alum Rock was named after a rock formerly thought to be composed of alum in nearby Alum Rock Park. In the 19th century and early 20th century Alum Rock was mostly fruit orchard land. During the 1940s and 1950s, developers began building housing and formed the community of Alum Rock. During that time, Alum Rock Avenue and a passenger railroad passed through the town on the way to Alum Rock Park. In the 1980s and 1990s, the neighborhood became older and increasingly populated with Latino immigrants as "white flight" affected the area of East San Jose. Today, Alum Rock remains a distinct community separated from the rest of San Jose. The magnitude 5.6 Alum Rock earthquake occurred just northeast of the community on October 30, 2007, the strongest to hit the region since the 1989 Loma Prieta earthquake. No significant damage or injuries were reported.
