Mennock is a small village or hamlet which lies 2 miles (3.2 km) south-east of Sanquhar on the A76, in Dumfriesshire, in the District Council Region of Dumfries and Galloway, southwest Scotland.

The village was known as 'Minnock Bridge' in 1886 and the river was recorded as 'Minnick Water' with its source 7 miles (11 km) away on the north-western slope of Lowther Hill.

The Mennock War Memorial has the names of those who served and who died from the village as well as those who attended the school and were killed in WWI.

[4] Glendyne lies about 2 miles (3.2 km) from Mennock and is famous as a onetime hiding place for persecuted Covenanters thanks to its isolation and its depth.

A small croft by the name of Ringbrae once stood near Mennock Wood, a path and footbridge connecting it to the village.

[12] The name 'Dempster' suggest a much older origin as a 'Dempster' until 1746 was the official at Scottish baronial courts responsible for executing the judicial decisions and announced the "doom" as the sentence was called.

An engineers track access point and materials storage area exists slightly to the south of the old depot's location.

The earliest recorded version of the Mennock Water name in 1660 is 'Minnock' and the derivation may be from the Scots Gaelic 'mèineach', meaning 'abounding in ore or mines'.

In British usage Mennock is technically a hamlet rather than a village as it has always lacked a formal dedicated church of its own.
