- Source: 1998 Montreal Alouettes season
The 1998 Montreal Alouettes finished in second place in the East Division with a 12–5–1 record. The Hamilton Tiger-Cats finished with the same record, but won the season series and thus, the tie-breaker. Hamilton also defeated the Alouettes in the East Final, denying the team a trip to the Grey Cup.
The 1998 season was significant with the signing of future all-time team passing leader Anthony Calvillo, the drafting of future Alouette touchdown leader Ben Cahoon, and longtime centre Bryan Chiu becoming a regular starter on the offensive line. Running back Mike Pringle became the first player to rush for over 2000 yards in a single season. The Alouettes also made a permanent move to Percival Molson Memorial Stadium on the campus of McGill University after dwindling attendance numbers at Olympic Stadium.
