Lough Conway is a very small freshwater lake in northwest Ireland.
The origin of the lake name is unknown, but (Irish: Loch Conbhuí) has the meaning "".
Lough Conway is located in Kiltubbrid parish in the county Leitrim. It connects with Drumaleague Lough by a 0.8km (00.5miles) navigable stretch of the Shannon–Erne Waterway. This elliptical shaped very lake is small, covering a surface-area of about 0.06km2 and measures 350m (1,150feet) from the north-east to south-west shore, with 140m (460feet) wide.
Fish present in Lough Conway include Pike. The pike population is the "native Irish strain" (Irish: liús meaning 'Irish Pike') not the other European Pike strain (Irish: gailliasc meaning 'strange or foreign fish'). The ecology of Lough Conway, and other county Leitrim waterways, are threatened by zebra mussel and other invasive species.
From at least the 18th century a sluice was used to reserve a water supply from Lough Conway for the nearby Corn Mill situated on Kilclaremore townland. This corn mill was "", so the branch drain between "" and Lough Conway was improved. The corn mill closed in the 20th century.
The primary human settlements near Lough Conway are the surrounding townlands of Kilclaremore and Drumruekill to the west, Loughconway to the north, and Kilclaremore on the south.
