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.
