Kilcornan (Irish: Cill Churnáin) is a civil parish in County Limerick.

Apart from Curraghchase, the ancestral home of the Victorian Poet Aubrey de Vere, the next most visited tourism site in Kilcornan is the Stonehall Visitor Park.

Lewis's Topographical Dictionary notes that the earliest identifiable settlements in Kilcornan were Danish.

A large part of the parish was granted to Hardress Waller, one of Cromwell's generals.

In 1551 the rector of the parish, William Casey, was nominated by James, the Earl of Desmond to be the first non-Catholic bishop of Limerick.
