Lower Penarth Halt was a station on the now completely removed double track branch from Penarth to Biglis Junction, Cadoxton in Glamorgan, South Wales. The station opened in 1888. It had two platforms, with shelters on each, and a substantial waiting room on the 'up' platform. It had no footbridge, though a level crossing was supplied. The Great Western Railway downgraded the station to a halt in 1935, a fate shared by most other stations on the branch.
