The 2010 IIHF World Championship Division III was a pair of international ice hockey tournaments organized by the International Ice Hockey Federation. The tournaments were contested between 14 and 18 April 2010. For the first time, the IIHF allowed eight teams, rather than six, to compete in Division III, which was handled by separating the teams into two groups. Group A was played in Kockelscheuer, Luxembourg, while Group B's games took place in Yerevan, Armenia. The process reverted to the single group of six teams the following year. The IIHF announced on 5 February 2010 that the Division III Group A championship would be moved from Athens, Greece to Kockelscheuer, Luxembourg after the Hellenic Ice Sports Federation announced they would not able to host the tournament after problems with government funding. Ireland and North Korea were both promoted to Division II for the 2011 World Championships. According to the IIHF, due to eligibility issues all games involving Armenia's became 5–0 wins for the opposing teams and Armenia was excluded from the final ranking.
