Kopperå is a village in the municipality of Meråker in Trøndelag county, Norway. The village lies about 7 kilometres (4.3 mi) east of the municipal center of Midtbygda and about 14 kilometres (8.7 mi) west of the Swedish border. The Meråker Line railway runs through the village and stops at the Kopperå Station. The village sits near the confluence of the rivers Kåpperåa and Stjørdalselva, and it is about 5 kilometres (3.1 mi) south of the lake Fjergen. The local Kopperå Chapel sits on the northwest edge of the village.

Kopperå had one of the best microsilica factories, Elkem Meraaker, a member of the Elkem Group. Elkem Meraaker (originally Meraaker Smelteverk) started to manufacture carbide in 1898, and was later re-built to manufacture microsilica. But in 2005 the company made the decision to end microsilica manufacturing. The factory ceased operations in summer 2006 and the buildings were taken down by 2008.
