Mary Clare Kennedy (fl. 1647) was the second Abbess of the Poor Clares of Galway. Kennedy became abbess sometime in the mid-1640s. Ó Muraíle has drawn attention to the fact that of the twelve sisters and two novices that founded the Galway convent, twelve had Anglo-Irish surnames yet two, including Kennedy, bore Gaelic surnames. Kennedy was succeeded by Browne in 1647 and was among the sisters when Galway surrendered to Cromwellian forces in April 1652. Her subsequent fate is unknown.
