The Town of Cambria is in the center of Niagara County.
New York State Route 93 passes through the town.
Some of the early settlers were from Wales, and gave the town the name of their origin.
The Town of Cambria was established in 1808 when Niagara county was formed. Cambria was the original town of Niagara County; all other towns were formed from its territory after 1812.
When Genesee County, New York was formed in 1802, all of Niagara County was included and was part of the Town of Batavia. Subsequently Erie County was created by removing the Towns of Willink and Clarence, both towns having been created from Cambria in Niagara County.
