The 1997 Super League season (also known as the Telstra Cup due to sponsorship by Telstra Corporation) was a breakaway professional rugby league football competition in Australia and the only one to be run by the News Limited-controlled Super League organisation. Eight teams which had broken away from the existing Australian Rugby League, in addition to the newly created Adelaide Rams and Hunter Mariners, competed over eighteen weekly rounds of the regular season. The top five teams then played a series of knock-out finals which culminated in a September grand final played in Brisbane between the Brisbane Broncos and the Cronulla Sharks.
