Cogan railway station is a railway station serving Cogan in the Vale of Glamorgan in Wales. It is located on the Vale of Glamorgan Line 2¾ miles (4 km) south of Cardiff Central on the way to Barry Island and Bridgend.
Until 1968 Cogan had two additional and separate platforms across the other side of the main Windsor Road, opened twenty years earlier in 1878 and located on the Penarth and Sully branch line, that extended from the Cogan Junction points around the coastline through Lavernock and Sully to where it rejoined the main line at Cadoxton. That through link was closed under the effects of the Beeching Axe and the rail spur now terminates at Penarth.
Dingle Road Halt and Penarth station remain open but the two platforms at Cogan were closed when the line was reduced to a single track spur. Most of the station buildings still stand but have been used by several private businesses including a shooting range, a garden centre, a second hand car lot and a marine chandlers. The area originally covered by the Cogan and Penarth dock's railway sidings and engine maintenance sheds now contains a large Tesco supermarket.
