Lough Kinale (Irish: Loch Cinnéile) is a freshwater lake in the north midlands of Ireland, situated on the borders of counties Longford, Westmeath, and Cavan. The lake measures approximately 2.4 km in length and 1.1 km in width, with a surface area of 1.95 km², and sits at an elevation of 62 m. It is a very shallow water body, with a maximum depth of around 4 m (13 ft).

The lake forms part of the River Inny system, receiving its inflow from Lough Sheelin and draining outward toward Lough Derravaragh. A smaller adjacent lake, Lough Derragh, is also connected to Lough Kinale via the Inny. The lake is divided into two distinct sections, almost separated by a central swampy area, which gives it a somewhat irregular character. The margins are lined with reed beds interspersed with calcium-rich marsh dominated by small sedges, creating a naturalistic shoreline environment.

The lake carries notable archaeological significance. A 9th-century book shrine — the largest and earliest of Ireland's medieval book shrines — was recovered by divers in 1986 from the lake's waters, near the site of a crannóg (an ancient island settlement). This history adds a layer of cultural interest for paddlers exploring the lake's edges.

The lake lies approximately 10 km east of Granard and is roughly equidistant from Cavan town, Longford town, and Mullingar, each around 25 km distant. Given its shallow depth and modest size, it is a manageable body of water, though the swampy central area and extensive reed beds along the margins are features paddlers should be aware of when planning routes or landings.
