Máire de Paor (6 May 1925 – 6 December 1994), née MacDermott, was an Irish historian and archaeologist who also worked as a researcher and presenter for the national broadcaster RTÉ.

She was educated in the Convent of Mercy in Buncrana before going to University College Dublin, where she completed a master's degree and a doctorate on early Christian archaeology and metalwork.

de Paor published her papers in the Proceedings of the Royal Irish Academy, Archaeologia, Seanchas Armagh and Comhar.

Her husband also worked in the university, and as a result of policies about married women, de Paor was forced to leave.

UCD created the Dr Máire de Paor Award for best PhD thesis[9].
