Dun Laoghaire Marina sits in the southwest corner of the historic harbour of Dun Laoghaire, on the scenic southern shore of Dublin Bay.

Protected behind two inner breakwaters within a larger 250-acre harbour formed by massive piers built in the early 1800s, the marina opened on St Patrick's Day 2001 and has grown to accommodate up to 820 boats.

It holds a Five Gold Anchor rating and maintains a minimum depth of 4 metres at low water springs, keeping it accessible at all states of the tide. Berths range from 6 to 30-plus metres in length.

The marina offers fuel (petrol and diesel), shore power, fresh water, and toilet and shower facilities. It is conveniently close to Dun Laoghaire town centre and well connected to Dublin city by train and bus, with stops directly in front of the harbour.
