The 2018 Hastings Deering Colts season was the 1st season of the under-20 competition, sponsored by Hastings Deering and run by the Queensland Rugby League. Replacing the National Rugby League's National Youth Competition, the draw and structure of the competition mirrored that of its senior counterpart, the Queensland Cup.
