HK Olimpija was founded in 2004 with the primary task of educating young players and promoting ice hockey in Ljubljana and its surroundings.

[2] The history of ice hockey in Ljubljana dates back to 1928, when SK Ilirija was founded.

In the 2020–21 season, Olimpija defended the AHL title and became the first club to win the competition multiple times.

[8] However, they failed to defend the national title, narrowly losing 3–2 in the final against their rivals HDD Jesenice.

[11] Derived from the city symbols, Olimpija's nicknames are Zmaji (The Dragons) and Zeleno-beli (The Green and Whites).

[12][13] In addition to fans from Central Slovenia and other parts of the country, Olimpija has two official supporters groups.

Ledeni zmaji (The Ice Dragons) are exclusively fans of the ice hockey club, while the Green Dragons mostly attend football matches of NK Olimpija and attend the most important matches and derbies of HK Olimpija.
