Arklow Marina sits on the north bank of the River Avoca in Arklow, County Wicklow, roughly midway along Ireland's east coast between Dublin and Carnsore Point.

The marina offers 42 berths in an inner basin plus a further 30 berths on riverside pontoons; visitors and vessels over 12 metres are advised to use the riverside pontoons.

The harbour entrance is deep and lit, accessible day or night on any state of the tide, with no significant off-lying hazards. The inner harbour provides well-sheltered berths capable of riding out severe weather.

Arklow Shipping, one of Europe's larger short-sea carriers, has its head office on the adjacent North Quay, reflecting the town's strong and continuing maritime tradition.
