Stenders Quarry (grid reference SO659183) is a 2.8-hectare (6.9-acre) biological and geological Site of Special Scientific Interest in the Forest of Dean, Gloucestershire, England, notified in 1966 and renotified in 1990.

The Quarry, which was gradually extended during the second half of the nineteenth century, provided material for the cement works.

The remains of an overhead tramway, which was built to carry the limestone across the road, can be seen on the eastern side of Stenders Quarry.

These include kidney vetch, cowslip, yellow-wort, ploughman's-spikenard (Inula conyza), large thyme (Thymus pulegioides), blue fleabane and the common spotted-orchid.

[5] Part of the site is covered by wild cherry, pedunculate oak, ash, dogwood, hawthorn, grey willow and dog-rose.
