Mount Pleasant is a small village in the south of Merthyr Tydfil County Borough, Wales. It lies about 1 km (2⁄3 mi) south of Merthyr Vale, along the A4054 road (the former route of the A470 to Cardiff) and between that road and the River Taff.

The village is also known as "The Black Lion" after the old signal box, controlling passenger and coal lines from Merthyr Vale Colliery to Cardiff on the Taff Vale Railway.
