McNulty is an Irish surname. It is derived from the Gaelic Mac an Ultaigh meaning "son of the Ulsterman". Usually considered a branch of the Ulaid ruling dynasty of Mac Duinnshléibhe (MacDonlevy), a branch of Dál Fiatach, who fled Ulaid to Ailech after the former's conquest in 1177 by the Normans. DNA analysis points to descent from other Ulaid families as well. After the Battle of Kinsale in 1602, some McDonlevys and McNultys migrated to the province of Connacht where their name is now also common.

==Origin== The name is said to have arisen from a branch of the ruling Ulaid dynasty of Mac Duinnshléibhe (MacDonlevy) who had migrated to what is now County Donegal in the Republic of Ireland after John de Courcy's conquest of Ulaid in 1177. Here some of the MacDonlevys were nicknamed Ultagh/Ultach. However, historical records such as the 1659 "Census" as well as Griffith's Valuation (1848-1864) show that concentrations of McNultys were found in parts of Ireland where the MacDonlevys had little presence, coupled with DNA analysis showing that the McNultys may actually derive from other Gaelic families that migrated from Ulaid and not just the MacDonlevy's. The names Ultagh/Ultach and Mac an Ultaigh applied to only those that fled Ulaid and was not used for those that remained.
