Cleggan (Irish: An Cloigeann meaning head) is a picturesque fishing village in County Galway, Ireland. The village lies 10 km (7 mi) northwest of Clifden and is situated at the head of Cleggan Bay.

A focal point of the village is the pier, built by Alexander Nimmo in 1822 and extended in 1908. Ferries leave the pier daily for Inishbofin (Galway), and there is also a ferry to Inishturk.
