Gormlaith ingen Flann mac Conaing

Gormlaith ingen Conaing mac Flainn (fl. 870) was a Queen of Tara, Ireland.

Gormlaith was a daughter of Conaing mac Flainn, King of Brega, and the unnamed daughter of Niall Caille and Gormflaith ingen Donncadha. Her known siblings included Cináed mac Conaing (died 851) and Flann mac Conaing (died 868), both of whom were Kings of Brega.

She was the first wife of Flann Sinna, High-King of Ireland, by whom she had Gormflaith ingen Flann Sinna and Donnchad Donn.

Via Gormflaith, she was ancestor to the O'Neill dynasty of Ulster. Donnchad Donn was the ancestor to the Ua Mael Seachlainn kings of Mide.
