Carn Brea is a civil parish and hilltop site in Cornwall, England, United Kingdom. The population of Carn Brea including Bosleake and Church Coombe was 8,013 at the 2011 census. The hilltop site is situated approximately one mile (1.6 km) southwest of Redruth. The settlements of Bosleake, Brea, Broad Lane, Carn Arthen, Carn Brea Village, Carnkie, Four Lanes, Grillis, Illogan Highway, Pencoys, Penhallick, Piece, Pool, Tolskithy, Tregajorran, Treskillard, Tuckingmill and West Tolgus are in the parish.

There are seventeen disused railway stations on the Cornish Main Line between Plymouth in Devon and Penzance in Cornwall, England. The remains of nine of these can be seen from passing trains. While a number of these were closed following the so-called "Beeching Axe" in the 1960s, many of them had been closed much earlier, the traffic for which they had been built failing to materialise.
