North Warren RSPB reserve is a nature reserve run by the Royal Society for the Protection of Birds (RSPB) in Suffolk, England. It lies on the Suffolk coast on the north edge of the town of Aldeburgh and to the south of Thorpeness and includes the Aldringham Walks area of heathland to the north. It is within the Suffolk Coast and Heaths Area of Outstanding Natural Beauty (AONB) and the Suffolk Heritage Coast area. Noted for its populations of Eurasian bittern, European nightjar and other bird species, it covers a range of coastal habitats and is protected with SSSI, SPA conservation status.

The 4.43 square kilometres (1.71 sq mi) site covers a mix of coastal habitats, with areas of grassland, lowland heath, reed bed, shingle, dune and woodland. Rare shingle flora such as sea pea, sea kale, sea holly and yellow horned-poppy can be found at North Warren. Key conservation bird species found at the site include Eurasian bittern, European nightjar, nightingale and western marsh harrier.

It is also an important over wintering site for wildfowl including large numbers of Eurasian wigeon, common teal and a flock of greater white-fronted geese. In 2007, three marsh harrier chicks fledged from three nests and seven nightjars, 23 pairs of woodlark, seven pairs of Dartford warbler and three booming bitterns were recorded.
