South Mountain is a colloquial name applied to an Appalachian Mountain range extending north and northeast along the south side of Lebanon Valley to the Lehigh Valley region of eastern Pennsylvania. South Mountain includes the southernmost cluster of peaks that straddle Berks, Lancaster, and Lebanon counties and the northernmost end of the ridge on which Lehigh University is built, in Bethlehem in the Lehigh Valley.

The mountain borders Emmaus just south of Allentown and comprises a ridge of low mountains passing east of Reading, and then extends due west.
