Arklow Marina sits on the north bank of the River Avoca, upstream of the commercial quays in Arklow, County Wicklow.

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 dangers. The inner harbour provides well-sheltered berths, making it a reliable refuge in poor weather.

Arklow Shipping, one of Europe's larger short-sea shipping companies, has its head office on the adjacent North Quay, reflecting the town's enduring maritime character.
