Loughinsholin (from Irish Loch Inse Ui Fhloinn, meaning 'lough of O'Lynn's island') is a barony in County Londonderry, Northern Ireland. Its southeast borders the northwest shore of Lough Neagh, and itself is bordered by seven other baronies: Dungannon Upper to the south; Strabane Upper to the west; Keenaght and Coleraine to the north; Kilconway, Toome Upper, and Toome Lower to the east.

The Sperrin Mountains rise to the west of Loughinsholin, with Slieve Gallion and Carntogher the two most notable mountains of the range in the barony. The Ballinderry River flows along the southern boundary of the barony, with the River Moyola cutting through the middle, both emptying into Lough Neagh. The largest settlement in the barony is town of Magherafelt.

The area of land that forms Loughinsholin has changed control several times throughout history. During the first millennium, it was part of the Cruithin over-kingdom of Ulaidh. It would then become part of the over-kingdom of Airgialla, founded by the Three Collas from their conquests in Ulster. One of the under-kingdoms of Airgialla was Ui Tuirtri, named after Fiachu Tuirtri, son of Colla Uais (one of the Three Collas), which stretched from the River Blackwater south of Dungannon to the River Bior (meaning water, modern day Moyola River), located half a mile north of Tobermore.
