The following is a provisional list of the
kings of Leinster who ruled the Irish kingdom of
Leinster (or
Laigin) up to 1632 with the death of
Domhnall Spainneach Mac Murrough Caomhanach, the last legitimately inaugurated head of the MacMurrough Kavanagh royal line. Today's province of
Leinster is considerably larger than the former kingdom.
