Combe Haven is a 156.1 hectare (385.7 acre) biological Site of Special Scientific Interest, located in East Sussex, England, around 3.5 kilometres (2.2 mi) west of Hastings. The site was notified in 1985 under the Wildlife and Countryside Act 1981.

The site consists of mainly alluvial meadows and Filsham Reed Bed, the largest reed bed in the county, creating a very important site for a variety of fauna.

A new road from Bexhill to Hastings opened in April 2016 which skirts the northern edge of Combe Haven. There were protests against the road's impact on Combe Haven.

Modern maps mark the small river which flows through the site as Combe Haven. This is the river which rises near Senlac Hill, the site of the Battle of Hastings and enters the sea in Bulverhythe at grid reference TQ 784 086. However other sources call this the River Asten.
