Bellemare participated at the 2010 IIHF World Championship as a member of the French national team.
He was also named to the French roster for competition at the 2014 IIHF World Championship.
In the nation's opening group game on 9 May 2014, Bellemare scored the game-winning shootout goal to give France a 3–2 victory over Canada, France's second-ever victory over the Canadians in 83 years.

In the 2016 World Cup of Hockey, Bellemare played for Team Europe, being the only player to represent France in the tournament.
Team Europe won silver, having lost to Canada 3-1 and 2-1 in the championship match.

In the 2017 IIHF World Championship, Bellemare was set to receive the Player of the Game award, scoring a goal and an assist in France's 5–1 win over Finland.
In an act of selflessness and respect, he waived acceptance of the award, urging it deserved to go to the French Team goalie, Florian Hardy, who had 42 saves.
