The 2021 Men's Ice Hockey World Championships was the 84th such event hosted by the International Ice Hockey Federation. Due to the ongoing COVID-19 pandemic, only teams in the championship division participated in this year's tournament. The competition served as a qualification tournament for the top (only) division placements in the 2022 competition.
After all events were cancelled in 2020, all teams remained in their respective divisions. Singapore was scheduled to be the newest national team to participate and has been assigned to Division IV. On 18 November 2020, the IIHF announced that they had cancelled the tournaments for Divisions I, II, III and IV due to the COVID-19 pandemic. The Championship Division was held from 21 May to 6 June.[1]
