The club was formed in 1990 as HC Örebro 90. While Örebro IK (ÖIK) existed, HC Örebro 90's goal was to make sure that ice hockey players who didn't get a spot in Örebro IK could still play ice hockey in Örebro. Following ÖIK's bankruptcy in 1999, several ÖIK players moved to HC Örebro 90; one player, Henrik Löwdahl, currently plays for the team (and has done so since ÖIK's bankruptcy). The club changed its name to Örebro HK in 2005.
The team promoted to the second-tier league Allsvenskan (now HockeyAllsvenskan) in the 2000–01 season, but were relegated to Division 1 in the 2003–04 season. The team would spend five seasons in Division 1 after the relegation. The team reached the Kvalserien qualification for HockeyAllsvenskan in the 2008–09 season and successfully promoted back to HockeyAllsvenskan, ending first in the Kvalserien qualification. The team ended tenth in the 2009–10 HockeyAllsvenskan season and thus missed the playoffs. In the 2010–11 season they improved significantly, finishing third in the standings and thus reaching the 2011 Kvalserien qualification for the top-tier league Elitserien/SHL. The team ended fifth in the qualification and thus failed to promote to Elitserien that year. Two years later, in the 2013 Kvalserien, the team finally managed to promote to the SHL. The team will make their SHL debut in the 2013–14 season. It will be their first SHL season in club history and the first SHL season with a team from Örebro since 1978–79.
