The River Maigue (/ˈmeɪɡ/ Irish: An Mháigh, meaning 'river of the plain')[1] rises in the Milford area of north County Cork, Ireland.

It flows through Croom and Adare before entering the Shannon Estuary (Irish: An tSionainn) just north of Ferry Bridge between Kildimo and Clarina, just west of Limerick city.

In ancient times the Maigue was central to the territories of the O'Donovans and their predecessors in Uí Chairpre Áebda (Cairbre Eva).

The beautiful slow song in Irish, ‘Slán le Máigh’, was written by Aindrias Mac Craith, a poet from the local area who lived in the 18th century.

The Morning Star is a little river which flows westwards through rich farmland through Bruff and Athlacca to join the Maigue north of Bruree.
