Neagh Lacus is one of a number of hydrocarbon lakes found on Saturn's largest moon, Titan.

The lake is composed of liquid methane and ethane,[1] and was detected by the Cassini space probe.

The lacus is located at coordinates 81.11°N and 32.16°W on Titan's globe,[2] in a region close to the north pole where most of Titan's lakes are located.

The lake is 98 km in length[note 1] and is named after Lough Neagh, in Northern Ireland.
