Leckhampton Hill and Charlton Kings Common () is a  biological and geological Site of Special Scientific Interest in Gloucestershire, notified in 1954.  There are five units of assessment.

The site is listed in the 'Cotswold District' Local Plan 2001-2011 (on line) as a Key Wildlife Site (KWS).

Location
The site is in the Cotswold Area of Outstanding Natural Beauty and is one of a series of unimproved Jurassic limestone grassland area which are located along the Cotswold scarp. It is south of Cheltenham and near the communities of Leckhampton and Charlton Kings, and has a north-facing aspect.  The site also includes disused quarry faces, and quarry spoil which has been vegetated.

Geology
The Leckhampton quarries expose the thickest single cross-section through the Middle Jurassic, Inferior Oolite strata of the area.  They are a major research interest, and there are many published accounts of the last 150 years.  Strata of some 60 m are exposed, and the large outcrops are of significant importance to those studying palaeontology or sedimentology, and for studying ancient environments generally.

Biology
The site supports a range of habitats which include unimproved calcareous grassland, woodland and scrub, cliff faces and scree slopes. The grassland is of major importance and it comprises a tall ungrazed sward.  This is dominated by tor-grass, upright brome,  meadow oat-grass, sweet vernal-grass and quaking grass. It is noted for its range of herbs which include salad burnet, common rock-rose, common bird's-foot-trefoil.  The quarry floors support wild thyme, dwarf thistle, yellow-wort and autumn gentian. The site supports many plants which are scarce at a national or county level.  These include fly orchid, musk orchid and purple milk-vetch.  It is one of a small number of sites which support meadow clary in the county.

Shrub areas support nesting birds such as meadow pipit and grasshopper warbler.  It is a shelter area for invertebrates and small mammals.

There are wooded areas of broad-leaved and coniferous trees including mature beech.  These areas support a woodland flora such as ivy broomrape, white helleborine and greater butterfly-orchid.

There is a reported population of adder.
