Which rugby league club won the first Super League Grand Final in 1998?

Wigan Warriors won the first Super League Grand Final in 1998.

The inaugural Super League Grand Final was played at Old Trafford in Manchester on 24 September 1998. Wigan defeated Leeds Rhinos 10–4, becoming the first champions of the competition’s new end-of-season showpiece. The result added another major honour to Wigan’s exceptionally successful history.

Super League had been launched in 1996 as a reorganized professional competition in Britain. Before the Grand Final era, league champions were determined through regular-season standings or different playoff arrangements. The 1998 final established the format in which the leading clubs competed for the title at a single high-profile venue.

The match is distinct from the 1998 Super League season table and from the earlier Premiership finals. Wigan’s victory also predates later Grand Final successes by St Helens, Leeds Rhinos and other clubs. Old Trafford became the regular final venue for many years, helping turn the event into one of the sport’s best-known annual occasions.
