Bangor (/ˈbæŋɡər/ BANG-gər; from Irish Beannchar [ˈbʲaːn̪ˠəxəɾˠ]) is a city in County Down, Northern Ireland, on the southern side of Belfast Lough. It is within the Belfast metropolitan area and is 13 miles (22 km) east of Belfast city centre, to which it is linked by the A2 road and the Belfast–Bangor railway line. The population was 64,596 at the 2021 census. Bangor was granted city status in 2022, becoming Northern Ireland's sixth city.

Bangor Abbey was an important and influential monastery founded in the 6th century by Saint Comgall. Bangor grew during the 17th century Plantation of Ulster, when many Scottish settlers arrived. Today, tourism is important to the local economy, particularly in the summer months, and plans are being made for the long-delayed redevelopment of the seafront; a notable historical building in the city is Bangor Old Custom House. The largest plot of private land in the area, the Clandeboye Estate, which is a few miles from the city centre, belonged to the Marchioness of Dufferin and Ava. Bangor hosts the Royal Ulster and Ballyholme yacht clubs. Bangor Marina is one of the largest in Ireland, and holds Blue Flag status.
