Southcote Junction is a railway junction in the English town of Reading. It is the point where the Reading to Basingstoke line diverges from the Reading to Taunton line, and is situated between the Reading suburbs of Southcote and Coley Park and some 2 kilometres (1.2 mi) to the south of Reading West station. A second adjacent junction, the Coley Branch Junction, formerly existed a few metres to the north where the Coley branch line diverged.
