Dublin

The name "Dublin" is in reference to the city of Dublin, Ireland, because of the large number of Irish who lived in the area. The post office formally adopted the name in the 1890s. The area was first called Alamilla Springs, named after a spring located near the modern intersection of Dublin Boulevard and Dougherty Road. Another explanation suggests that the name may have developed from local references at the crossroads, either to a pair of inns known as the “Double Inns,” or to wagon drivers who would “double” their teams of horses before climbing a nearby hill.

Its 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.
