1998–99 ISL season

The 1998–99 Ice Hockey Superleague season was the third season of the Ice Hockey Superleague (ISL). Having reached a sponsorship deal with Sekonda, the league was now formally known as the Sekonda Ice Hockey Superleague.

Basingstoke Bison left the league and joined the British National League. The London Knights were formed and joined the ISL playing out of London Arena. The Newcastle franchise also changed their name from the Newcastle Cobras to the Newcastle Riverkings.

Losing the [aily Express sponsorship, the Express Cup was renamed the Challenge Cup. The competition was also integrated into the league fixtures with the first round of games between teams (home and away) counting towards the Challenge Cup table and the league table. The league season was therefore increased to forty-two rounds.
