List of undrafted NHL players with 100 games played

Players whose professional careers began before the 1969–70 season who were not drafted are not considered to be undrafted for purposes of this article, owing to NHL sponsorship of major junior hockey existing prior to that season.

[1] Also not included in this list is Wayne Gretzky, who was one of the Edmonton Oilers priority selections when they entered the NHL in 1979 and thus was never eligible to be drafted by an NHL team.

[2] Under existing rules he would have been removed from the Oilers and placed into the NHL Entry Draft since no team held his NHL rights, but the Oilers were allowed to keep Gretzky as one of their priority selections and were forced to choose last in each round of the 1979 NHL Entry Draft as further compensation.
