Ryan is a common Irish surname, as well as being a common given name.
There are several possible origins for the surname. In certain cases it can be a simplified form of Mulryan. In some cases the surname may be derived from the Irish Gaelic Ó Riagháin (modern Irish Ó Riain), meaning "descendant of Rían"; or Ó Maoilriain "descendant of Maoilriaghain", or Ó Ruaidhín "descendant of the little red one". The old Gaelic personal name Rían is of uncertain origin. It may be derived from the Gaelic rí, meaning "king".
The surname Ryan has been confused with the surname Regan, which is derived from Ó Ríagáin, meaning "descendant of Riagán".
