Great Glen is a village and civil parish in the Harborough district of Leicestershire, England. It is 2 miles south of Oadby and about seven miles south-east of Leicester. The population of the civil parish at the 2011 census was 3,662. Its name comes from the original Iron Age settlers who used the Celtic word glennos, meaning "valley", and comes from the fact that Great Glen lies in part of the valley of the River Sence. The "Great" part is to distinguish the village from Glen Parva.

The nearest watercourse on the river map is the River Sence, about 10 m from the middle of Great Glen's gauges. It flows into the River Soar about 19 km downstream.
A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on the River Sence nearest the middle of Great Glen's gauges. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
