Crotty (and variations O'Crotty, Crotti, Crottee, etc.) are anglicisations of the Irish name Ó Crotaigh – 'Descendant of Crotach'. The name dates from medieval times, to the pre-Norman kingdom of Thomond ('North Munster') where the Dál gCais (in English: 'Dalcassian') clan, centred on the regional rulers – the Uí Briain (O'Brien) family – were dominant. The Crottys were one of eight septs of the O'Briens (i.e. descended via the female line – hence the different surnames). They settled in western County Waterford and eastern County Cork.

Spelling variations include Crotty, O'Crotty, Crotti, Crothon, Crotton, Crotone, Crottee, Crottey, O'Crottey, O'Crottee, O'Crottie, Croddy, and Cratty. Other non-anglicised versions in use include Crothaigh, Chrothaigh etc. The other seven related septs of the O'Briens are the families: Bernard, Consadine, Lysaght, MacMahon, O'Mahoney, Padden/MacFadden and Plunkett.
