She was named USA Women's Player of the Year in 1996. Granato was the captain of the U.S. women's hockey team that won a gold medal in the 1998 Winter Olympics. On February 8, 1998, she scored the first ever Olympic goal for the U.S women's hockey team. In 205 career games for the national team, Granato had 186 goals, 157 assists, and 343 points. As of 2021, she is the team's all-time leading scorer. Granato was cut from the US National team unexpectedly before the 2006 Olympics, bringing controversy to the decision after being a part of the program since its inaugural season and all-time leading point scorer. The US team subsequently lost its Olympic semifinal match to Sweden, its first-ever international loss to a team other than Canada, and brought home the bronze medal. 

Granato has been a recipient of the Lester Patrick Award (2007), and she has been inducted into the International Hockey Hall of Fame, the US Hockey Hall of Fame, and one of the first women to be inducted into the Hockey Hall of Fame in November 2010.
