Killaloe is a parish in County Clare, Ireland, and part of the Scáth na Sionnaine grouping of parishes within the Roman Catholic Diocese of Killaloe.

As of 2021[update], the co-parish priest is James Grace.

The church replaced an earlier chapel.

The church grounds contains the Oratory of St. Lua that was moved there because of the impending flooding of its original location Friars Island due to the Shannon hydroelectric scheme.

This church was built in 1832 and was nearly completely rebuilt during the renovations in 1970.
