Waterville, historically known as Carrean (Irish: an Corráin, meaning "the crescent"), is a village in County Kerry, Ireland, on the Iveragh peninsula. The town is sited on a narrow isthmus, with Lough Currane on the east side of the town, and Ballinskelligs Bay on the west, and the Currane River connecting the two.
The town's name in Irish refers to the river in the case of "The Little Whirlpool", or "The Sickle" refers to the shape of Ballinskelligs Bay on which the town sits; the name however has been transplanted onto the lake with the Irish name being Loch Luíoch or Loch Luidheach.
The Butler family built a house at the mouth of the River Currane in the latter part of the 18th century. They named their house and estate Waterville. The village that developed on the estate during the first half of the 19th century was also named Waterville.
The N70 Ring of Kerry route passes through the town. Waterville has a population of 538 (CSO 2002).
