Farnham Mires is a Site of Special Scientific Interest, or SSSI, to the west of the village of Farnham, North Yorkshire, England. It consists of a spring-fed marshy fen or mire with reeds and sedge, and drier calcareous grassland containing a diverse range of flora. It has a history of poaching and fox hunting, but since the late 19th century, the attention of botanists has been drawn to its large variety of flowering plants. It has received some consideration on this account since 1944, and from 1954 it was designated SSSI status. This site has no facilities, and is not open to the public.
