The 1989 Panasonic Cup was the 16th edition of the NSWRL Midweek Cup, a NSWRL-organised national club Rugby League tournament between the leading clubs and representative teams from the NSWRL, the BRL, the CRL and Papua New Guinea. This was the final season of the competition, which was replaced by the Tooheys Challenge Cup the following year.

The Amco Cup was a mid-week rugby league competition held in Australia between 1974 and 1989. The format was usually a straight knock-out, but various group formats were used between 1979 and 1982. It aired on Channel Ten with Ray Warren and Keith Barnes the commentators for many years. The concept was created by Colin McLennan.
