About Martinez, California

Martinez is a city in and the county seat of Contra Costa County, California, in the East Bay of the San Francisco Bay Area. The city is named for Ygnacio Martínez, a Californio ranchero and soldier who founded the community.

Established in 1876, Martinez has a population of 35,824 at the 2010 U.S. Census. The City’s roots can be traced to the late 1840’s, when it served as a ferryboat transit point across the Carquinez straits on the way to the gold fields. By the time of its incorporation, Martinez had evolved into one of the area’s most significant trading posts and shipping ports.

As one of California’ first towns, Martinez retains a strong sense of history and family. The renowned naturalist John Muir made Martinez his home for nearly a quarter of a century and in 1914, the year of Muir’s passing, the legendary baseball great Joe DiMaggio was born here. One of the unique aspects of Martinez is its architecture. Many of the downtown shops still retain their early 20th Century look and charm, with some homes dating back more than 125 years.

Respecting its past but with an eye to the future, Martinez has modernized both its infrastructure and its downtown. The City opened an award-winning Intermodal Facility in 2001 that has become a popular stop along the Amtrak line. It also completed a major restoration of Alhambra Creek that beautifies the downtown and controls flooding, and has embarked on a program to make Martinez a cultural-historical attraction as the home of the John Muir Festival Center.
