Karine Sergerie (born February 1, 1985) is the 2007 world champion in women's lightweight (under 63 kg) taekwondo.

Sergerie won a silver medal at the 2003 World Taekwondo Championships.

One set of requirements said she needed to win a gold at the Pan-American Games to qualify, while another one did not.

Although she did win a bronze medal at the 2003 Pan-Am Games, the Taekwondo Federation of Canada ruled it was not enough.

In 2008, Karine advanced to the final where she competed against Hwang Kyung-Seon for the gold medal.
