Area of Outstanding Natural Beauty (Northern Ireland)

Map of the eight Areas of Outstanding Natural Beauty in Northern Ireland

An Area of Outstanding Natural Beauty (AONB) in Northern Ireland, is an area of countryside that has been designated for statutory protection, due to their significant landscape value, by the Northern Ireland Environment Agency. There are eight AONBs in Northern Ireland; Antrim Coast and Glens, Binevenagh, Causeway Coast, Lagan Valley, Mourne, Ring of Gullion, Sperrin, and Strangford and Lecale.

Areas of Outstanding Natural Beauty in Northern Ireland are designated under the Amenity Lands Act (Northern Ireland) 1965 or the Nature Conservation and Amenity Lands (NI) Order 1985. Lagan Valley AONB is the oldest designated AONB in Northern Ireland designated in 1965, it is also the smallest, while Sperrin AONB is the largest AONB. The newest change was in 2010, when Strangford Lough and Lecale Coast AONBs were merged as the Strangford and Lecale AONB.

It shared the name with a similar designation used in England and Wales, until 2023 when those areas adopted the "National Landscape" terminology, although their legal name still remains AONB.
