Lough Owel is a lough in the Midlands of Ireland, situated north of Mullingar, the county town of Westmeath. It is a deep lake, well known amongst anglers, and holds a few char along with brown trout. Water from Lough Owel feeds the Royal Canal, a canal crossing Ireland from Dublin to the River Shannon. Access to the lake can be gained from a carpark and pier to the south of the N4 Mullingar to Longford route.

Lough Owel and Lough Ennell are two of many lakes that form the river Brosna drainage basin. The Brosna is a Leinster tributary of the Shannon, flowing through Mullingar and Kilbeggan, both in Westmeath, and from there through the town of Clara (County Offaly) into the Shannon.

The Viking chieftain Turgesius was drowned in Lough Owel by Máel Sechnaill mac Maíl Ruanaid in 845.
