Since 1950, Coagh has formed part of the Mid Ulster constituency for
Parliamentary elections, with this constituency also being used for elections to the
Assembly and other devolved bodies from 1973 onwards. In Parliament, Mid Ulster has been represented by the
abstentionist Sinn Féin since
1997, and in devolved elections Sinn Féin has been the largest party in the constituency since the
1996 election to the talks forum. In local government, Coagh has been part of
Mid Ulster District Council since it succeeded
Cookstown District Council in 2015. Coagh sits within the ward of the same name in
Cookstown DEA. Councillors for this DEA were first elected in 2014 and sat as part of a shadow council until Mid Ulster District Council formally took over in 2015. While a part of Cookstown District Council, Coagh previously sat within the ward of the same name in
Ballinderry DEA from 1981 onwards (with Ballinderry DEA having succeeded the earlier
Cookstown Area B which existed from 1973 to 1981). In both of these DEAs, Sinn Féin has been the largest party since 2011, and were joint-largest in 2005, when Ballinderry DEA was uncontested due to the number of candidates being same as the number of available seats, and no election was held. On this occasion, Sinn Féin and the SDLP won two seats each, out of the six available. Since 1973, Coagh has been represented by the following councillors: ==Notable people==
