The River Annalee (Irish: Abhainn na hEoghancha) is a river in County Cavan, Ireland. The source of the river is Lough Sillan near Shercock from which it flows westwards through Lough Tacker, and south of Cootehill, until it reaches Butlersbridge. To the west of the village the river then flows through a series of lakes, before its confluence with the River Erne.
The Bunnoe and Laragh Rivers are two main tributaries that join the river below Cootehill, where it is also joined by the Dromore River.
The Irish name for the river is Abhainn na hEoghanach, which originates from the name of the historical province to the north of the river known as An Eoghanach. The anglicised name of the river derives from one of the townlands through which it flows, namely Annaghlee (Eanach Lao).
Fishing is quite popular at Deredis near Butlersbridge and upstream of Cootehill in the stretch below Knappagh Bridge. Catches include Perch, Pike, Roach and Bream with Trout to over 3 pounds being reported.

The catchment area to the gauging station at Butlersbridge is 774 square kilometres (299 sq mi), which with an annual average rainfall of 1,020 millimetres (40 in), yields an average flow of 13.7 cubic metres per second (480 cu ft/s).
