Marina Kuptsova, Russian high jumper
Marina Kuptsova (born December 22, 1981 in Moscow) is a Russian high jumper who won a silver medal at the 2003 World Championships. She is also a former European indoor high jump champion. Her personal best jump of 2.02 metres was achieved in Hengelo in June 2003, a year when she also won the national championship.

She set a personal best of 2.00 m to win the 2002 Hochsprung mit Musik, and returned the following year with a season's best of 2.02 m to score a second victory.

She missed 2004 because of an Achilles tendon injury and spent the 2005 season trying to return to her best but she only managed 1.92 metres, which, however, was enough for a second place in the Russian championships.
