Maigh Seóla (Irish pronunciation: [mˠəi ˈʃoːl̪ˠə]), also known as Hy Briuin Seola, was the territory that included land along the east shore of Lough Corrib in County Galway, Ireland.
It was bounded to the east by the Uí Maine vassal kingdom of Soghain and extended roughly from what is now Clarinbridge in the south to Knockmaa Hill in the north.
However in later times the line which would become the Muintir Murchada, under the O'Flaherty chiefs, monopolized the kingship.
After the de Burgo / Burke family became established in Maigh Seola the territorial term Iar Connacht was only used to denote the territory of the O'Flahertys west of Lough Corrib and Lough Mask.
