Quothquan (also formerly spelled Couth-Boan, meaning "the beautiful hill";, pronounced , meaning "the common" ) is a village in Libberton parish, South Lanarkshire, Scotland. It is 3 + 1/4 mi northwest of Biggar, and 7 + 1/2 miles southeast of Lanark. To the southwest is the 1098 ft hill Quothquan Law, topped by the remains of a hill fort. The hill comprises two elements, one is an enclosure to the southeast which is around 400 by. The other is a lower larger annexe to the northwest, with double ramparts and a medial ditch which has mostly been filled in.

Community facilities

Quothquan has a village hall near the remains of the graveyard and the ruins of a small church. The original church was recorded in use as a schoolroom after 1724. A new church in the village was paid for in 1903 by Glasgow shipowner Sir Nathaniel Dunlop, who lived nearby.
