Cambria is an unincorporated community in Washington Township, Wayne County, Iowa, United States. It has never been incorporated, but it has existed since 1849. Although Cambria had the first post office in the county, its post office has since been closed, and its residents now have rural Corydon addresses. In 1879, when a branch of the CB&Q Railroad was built one mile west of the existing town, Cambria was replatted and moved to the railroad.
