The Levern Water (Scottish Gaelic: Uisge Labharain) is a small river in East Renfrewshire and Glasgow, Scotland.

It rises in the Long Loch and flows generally north and east, past the towns of Neilston and Barrhead, for a total distance of 9 miles (14 km).

[2] The source of Levern Water is Long Loch in East Renfrewshire,[3] from which it emerges at the north-eastern tip, at coordinates 55°44′35″N 4°25′33″W / 55.74313°N 4.42588°W / 55.74313; -4.42588.

[5] The river continues west to the smaller Commore Dam reservoir, from which it emerges due north, gradually turning towards the northeast.

[4][1] It continues into the suburb of Pollok[4] and joins the White Cart River near Crookston Castle, which was where Mary, Queen of Scots, fled following the Battle of Langside in 1568.
