Roydon Woods is a 294.9-hectare (729-acre) biological Site of Special Scientific Interest near Brockenhurst in Hampshire.

[1][2] It is a nature reserve managed by the Hampshire and Isle of Wight Wildlife Trust[3] and is part of New Forest Special Area of Conservation.

[4] A large part of these woods are ancient, but other areas are former oak and hazel coppice planted in the nineteenth century.

There are also areas of hornbeam and species-rich aldercarr.

The SSSI also includes a stretch of the Lymington River and many open glades.
