Carharrack (Cornish: Karardhek) is a civil parish and village in west Cornwall, England, United Kingdom.

[6] The first is that the name refers to a dwelling of religious purpose, a meeting place for travellers, originating from Carharrack's proximity to the pilgrimage trail between Canterbury and St Michael's Mount, which is known to have passed through the nearby villages of St Day to the north and Lanner to the south.

Boom years for the village were in the first half of the nineteenth century, with the expansion of the local mines which at peak employed several thousand people: Carharrack was the closest settlement and provided plenty of space for building.

The mines were served by the Redruth and Chasewater Railway (an early narrow gauge line) which connected them to quays at Devoran on Cornwall's south coast.

Carharrack is the type locality for the copper-arsenate mineral Olivenite, a crystalline lustrous rock which often has a green or olive hue.

There have been Cornish wrestling tournaments held in Carharrack in a field adjoining the Steam Engine Inn.
