Falmouth (/ˈfælməθ/ FAL-məth; Cornish (SWF): Aberfala) is a town, civil parish and port on the River Fal on the south coast of Cornwall, England, United Kingdom.
Falmouth was founded in 1613 by the Killigrew family on a site near the existing Pendennis Castle. It developed as a port on the Carrick Roads harbour, overshadowing the earlier town of Penryn. In the 19th century after the arrival of the railways, tourism became important to its economy. In modern times, both industries maintain a presence in Falmouth and the town is also home to the National Maritime Museum Cornwall, a campus of Falmouth University and Falmouth Art Gallery. At the 2021 census the parish had a population of 24,032.
