The club was established in February 1984 as Kiekko-Espoo and played their first season in 1984-85 in the Finnish Second Division. In 1988, they achieved promotion to the Finnish First Division and in 1992, they celebrated their promotion to the SM-liiga by beating Joensuun Kiekkopojat with a 3-2 series win in a best-of-five format. Tero Lehterä scored the winning goal and Jere Lehtinen assisted.
Kiekko-Espoo ended its first two seasons in SM-liiga in 11th place out of 12 teams. In the 1994-95 season, the team made the playoffs for the first time, losing to Lukko in quarter-finals. In 1997-98, Kiekko-Espoo caused a huge upset by beating regular season winner TPS in the quarter-finals. Kiekko-Espoo ended the season in fourth place. In the next summer, the team name was changed to the Espoo Blues. The name came from the dominant colour of their home jersey.
During the 1998-99 season, the team moved to its current home, LänsiAuto Areena (renamed in 2009 to Barona Areena due to sponsorship change). The first seasons in their new home were difficult despite the team signing many big names. The Blues missed the playoffs in 2001 and 2005. In 2002-03, the Blues had their best regular season, finishing in fourth place, only to lose against eventual champion Tappara in overtime of the seventh quarter-final.
The team took a step forward in 2006-07 when they reached the semi-finals for the first time, although they lost against Kärpät in three straight games, and lost the bronze medal game against HPK. During the 2007-08 season, the Blues set a new team record by winning 12 games in a row. They finally ended the regular season in second place and beat local rivals HIFK in the quarter-finals and other local rivals Jokerit in the semi-finals, proceeding to the finals and thus ensuring their first medal ever. The team eventually ended up second after losing in the finals to Kärpät.
In the next season, the team was again second after the regular season, but lost against Kärpät in the semi-finals, as well as the bronze medal game against KalPa. The season also included participation in the Champions Hockey League, where the Blues lost in the semi-finals against eventual champion ZSC Lions of Switzerland. The 2009-10 season was difficult for the team, and the Blues failed to reach the quarter-finals. In 2010-11, the team ended the regular season in ninth place and then beat eighth-placed Kärpät in the wild card round of the playoffs. The team then made history by becoming the first team in the SM-liiga to advance from the wild card round to the semi-finals, eventually beating Ässät in six games. In the semi-finals, the Blues continued their string of upsets and beat regular season winners JYP in five games. In the finals, HIFK swept the series in four games, and the Blues were awarded the silver medal for the second time in team history.
In the 2011-12 season, the Blues finished eighth in the regular season. After beating Lukko in the wild card round, the team faced KalPa in the quarter-finals. The Blues made history again, becoming the first team in SM-liiga history to win the series after being down 0-3. In the semi-finals, the Pelicans beat the Blues 4-1.
After declining ticket income and increasing expenses after a reacquisition by Jääkiekko Espoo Oy in 2012, the Blues were declared bankrupt in March 2016. Their final ranking in the 2015-2016 season was 15th, the lowest in the league.
16 players have been named Captain of the team.
