Wortham Ling is a 53.2-hectare (131-acre) biological Site of Special Scientific Interest north of Wortham in Suffolk.

[1][2] This site has acid grassland and dry heath on a sandy soil.

Some areas are intensely grazed by rabbits, producing a very short sward which is a suitable habitat for lichens and mosses.

Butterflies include many graylings.

[3] There is access to the site from several roads and footpaths.
