Map - Dublin, California (Dublin)

Dublin (formerly, Amador and Dougherty's Station) is a suburban city of the East Bay in California. It is located within the Amador Valley of Alameda County's Tri-Valley region. It is located along the north side of Interstate 580 at the intersection with Interstate 680, roughly 35 mi east of downtown San Francisco, 23 mi east of downtown Oakland, and 31 mi north of downtown San Jose.

It was referred to as "Dublin" in reference to the city of Dublin, Ireland, because of the large number of Irish who lived there. The post office formally adopted the name in the 1890s.

The population was 72,589 as of the 2020 census, which had grown from 46,063 in 2010. In 2013, Dublin was the second fastest-growing city in the state of California, behind only Santa Clarita. In 2019, census data showed Dublin as one of the fastest-growing cities in the country. Dublin was formerly home to the headquarters of Sybase, Inc (now part of SAP SE) and is currently home to the headquarters for CallidusCloud, Patelco Credit Union, Ross Stores, TriNet, Medley Health, Challenge Dairy and Arlen Ness.

In 1835, José María Amador was granted 16,500 acres for his service as a Mexican soldier and in Mission San Jose where he was an administrator in the valley which was named Amador Valley after him. In 1850, Irish settlers bought land from Amador and founded a town.

Several historical sites are preserved and located where Dublin Boulevard is crossed by Donlon Way, itself formerly the northernmost segment of the main road to Sunol and Niles Canyon (present-day Foothill Road):

* The Murray Schoolhouse (established in 1856 with 50 pupils)

* Green's Store (opened in 1860) current home of the Dublin Church of Christ.

* The old cemetery was formally established in 1859, although people had been buried in the churchyard for years before 1859.

* Old St. Raymond's Church (built 1859), is listed on the National Register of Historic Places

Dublin Boulevard, a generally east–west road running just north of Interstate 580, was a part of the Lincoln Highway and later U.S. Route 50. The street formerly curved southward near today's Hansen Drive to follow present-day Dublin Canyon Road toward Hayward.
