This is a list of champions' voice actors based on the voice actor forum post,[1][2] which was completed with help from the League of Legends community and Riot staff. Skins with complete voice overs, commonly associated with legendary skins, have been given their own cells to clarify that some voice overs may not be done by the same voice actor. Some voice actors may be unknown so that way they cannot be locked into contracts as easily and therefore chose to have their names withheld.
