Mac Raghnaill is masculine surname in the Irish language. The name translates into English as "son of Raghnall". The surname originated as a patronym, however it no longer refers to the actual name of the bearer's father.

The name Raghnall is a Gaelic derivative of the Old Norse personal name Røgnvaldr / Rǫgnvaldr / Rögnvaldr. Variant forms of the surname include Mac Rághnaill and Mac Raonaill. These three surnames can be Anglicised variously as: MacRannall, MacRanald, MacRandell, MacCrindle, MacReynold, MacReynolds, Randalson, Rondalson, Reynoldson, Rannals, Randals, Randles, Ranolds, and Reynolds. The Irish surnames are borne by numerous unrelated families; some are of Irish origin, others of Scottish origin, some are of English origin, and some may be of Norwegian and or Danish origin.
