Groomsport (from Irish Port an Ghiolla Ghruama 'port of the gloomy servant') is a suburb of Bangor in County Down, Northern Ireland.

Groomsport has developed as a centre for water and shore-based recreation with improved facilities for activities such as sailing and power boating.

Groomsport still retains the identity and character of a small harbour village with its pier and sheltered anchorage together with its historic street pattern.

Indeed, Groomsport narrowly missed out on New World fame when the ship Eagle Wing set out from the port, with 140 men, women and children, to attempt an early trip to North America in 1636 only to be defeated by bad weather after eight weeks at sea.
