"I couldn't think of a coach more suited to this role, given Mal's achievements as a former Kangaroos captain and his understanding of what representing Australia means," Smith said.
"He has a proven record at representative level, as well as a tremendous ability to help his players perform at the highest level."
NRL head of football Todd Greenberg said the appointment was the first move towards winning the 2017 Rugby League World Cup.
The announcement was made at Rugby League Central in Moore Park today and brings an end to Meninga's record-breaking reign as Queensland coach with long-time Kevin Walters expected to be named Maroons mentor.
