Gurney Slade quarry, {{gbmapping|ST626497}} is a limestone quarry near Gurney Slade between Binegar and Holcombe, on the Mendip Hills, Somerset, England.

Gurney Slade quarry exhibits pale to very dark grey carboniferous limestone overlain by red and purple-coloured Triassic breccias and marls with a small faulted block of overlying Lower Jurassic breccias forming an angular unconformity with the carboniferous limestone. There is abundant vertical sediment infilling fissures and joints (Neptunian Dykes). The rocks contain varying amounts of calcite mineralisation, and there is common fossil material associated with the Carboniferous and Jurassic limestones.{{cite web | title=Gurney Slade Quarry Geodiversity | url=http://www.somerset.gov.uk/somerset/ete/countryside/geodiversity/index.cfm?override=subtopic&infoid=4649 | work=Somerset County Council | access-date=2 February 2007}} The limestone within the quarry dips to the south-east at around 30°.{{cite web|title=Gurney Slade and Emborough|url=http://www.bgs.ac.uk/mendips/localities/gurneyslade.html|publisher=British Geological Survey|access-date=7 September 2011}}
