Ballinderry (from Irish Baile an Doire, meaning 'town of the oak wood') is a small civil and ecclesiastical parish on both sides of the County Londonderry / County Tyrone border in Northern Ireland. It is a rural parish of about 350 houses and lies on the western shores of Lough Neagh.
The parish contains two small villages: Ballylifford and Derrychrin, which are of relatively close proximity to Cookstown, Coalisland, Magherafelt and Dungannon. They are also very close to the settlements of Ardboe, Moortown, The Loup and Ballyronan.
Ballinderry River flows into Lough Neagh at Ballinderry. The river has formed the border between the two counties of Derry and Tyrone since the creation of the former. It is regarded by anglers as one of the best trout rivers in Ulster, and is also good for salmon. One variety of trout, known as dollaghan, is native to the Lough Neagh area. Canoeing is also popular along the river and canoe steps have been built at several points to aid the sport's participants.
Due to its location on the shores of Lough Neagh, fishing was historically the primary source of income for many local people.
Ballinderry gives its name to one of the three electoral areas that make up Cookstown District Council. Two councillors live in Ballinderry: Michael McIvor (Sinn Féin) and Patsy McGlone (Social Democratic and Labour Party). Sinn Féin has a branch in the area, known as the Volunteers Heron/Wilkinson/McNally Cumann.
