Kelly /ˈkɛli/ is a surname in the English language. The name has numerous origins. In some cases it is derived from toponyms located in Ireland and Great Britain, in other cases it is derived from patronyms in the Irish language.


In many cases Kelly is an Anglicisation of the Irish surname Ó Ceallaigh (IPA [oːˈcal̪ˠiː]), which means "descendant of Ceallach " or it can also mean warrior or fighter. The personal name Ceallach has been thought to mean "white-headed", but the current understanding is that the name means "frequenting churches", derived from the Irish ceall.[1] In other cases the surname Kelly is an Anglicisation of the Irish Ó Cadhla, which means "descendant of Cadhla".[2] The O’Kelly or Kelly of the Clan Brasil Mac Coolechan originated as a chieftain clan of the Ulaid.[3]

The surname can also be derived from several place names. For example, the surname can be derived from two places in Scotland: Kelly, near Arbroath; and Kellie, in Fife. The surname can also be derived from a place name in England: Kelly, in Devon. This place name is derived from the Cornish celli, meaning "wood" or "grove".[4]


The surname is one of the most prevalent surnames in Ireland. It is also very common in Galloway, and the Isle of Man.[4] The name O'Kelly, Kelly, Kelley, Kellie and the Gaelic form O'Ceallaigh, is the most common surname in Ireland. There are approximately half a million people worldwide who bear this name. Up until the 10th century surnames were not used in Ireland. The name O'Kelly did not spring from a single source, but arose independently in several areas in Ireland, also in Scotland and the Isle of Man and in England. In other areas, notably in Cornwall, Isle of Man and probably in Antrim, the name Kelly arose from Celli, meaning man of the woods.[5]
