The Dean of Limerick and Ardfert is a Church of Ireland official based in the Cathedral Church of St Mary's in the united diocese of Limerick, Killaloe and Ardfert.

There had been two separate deans, Dean of Limerick and Dean of Ardfert, until the position was united in 1987. The Dean of Ardfert had been based at Ardfert Cathedral (a.k.a. St Brendan's Cathedral), until it was destroyed by fire in 1641.

The current incumbent, since 2017, is The Very Reverend Niall Sloane.
