Ó Cuív was at the centre of a controversy surrounding the official name of An Daingean / Dingle, a small Gaeltacht town in west County Kerry. The residents of the town held a plebiscite in November 2006, to determine which version of the town name should be used. Ó Cuív originally signalled that he was happy to abide by the locals' decision, but then said that the name could not legally be changed back to Dingle, following advice from the Attorney General of Ireland.
