In the 1980s, Heerenveen twice made the promotion playoffs, but were unsuccessful both times. It finally reached the Eredivisie in 1990, becoming the first Frisian club to reach the top level, at the expense of near-neighbours Cambuur. The achievement was overseen by Frisian coach Foppe de Haan. Heerenveen's first season in the Netherlands' top division was not at all successful and it was relegated, before returning in 1993, though they reached the final of the KNVB Cup while still an Eerste Divisie club. Having established itself as a top-flight club, Heerenveen moved to a new stadium, named after their most celebrated player, the Abe Lenstra Stadion, and reached the final of the KNVB Cup for a second time. The 1998 semi-final in the cup competition was lost to Ajax. Because Ajax and the other finalist, PSV, had both qualified for the cup final, a decision match was needed to fill in the vacant spot for the next season's UEFA Cup Winners' Cup. Heerenveen had to play against the other losing semi-finalist, Twente. Heerenveen won that match in which Ruud van Nistelrooy scored his last goal for Heerenveen. The match ended 3–1.
