Oksana Aleksandrovna Chusovitina (Russian: Оксана Александровна Чусовитина; born 19 June 1975) is a world and Olympic level gymnast who has competed for the Soviet Union, Uzbekistan, and Germany.

Chusovitina's career as an elite gymnast has spanned more than a quarter century. She won the USSR Junior Nationals in 1988 and began competing at the international level in 1989, before many of her current rivals were even born. She is the only female gymnast ever to compete in seven Olympic Games, and is one of only two female gymnasts to compete at the Olympics under three different national teams: the Unified Team in 1992; Uzbekistan in 1996, 2000, 2004, and 2016; and Germany in 2008 and 2012. Chusovitina has also competed in 10 World Championships, three Asian Games and three Goodwill Games. Chusovitina holds the record for the most individual world championships medals on a single event (nine, on the vault).

Chusovitina is one of a few women, along with Cuban Leyanet Gonzalez, Soviet Larisa Latynina, and Dutch Suzanne Harmes, to return to international competition after becoming a mother. Australia's head women's coach, Peggy Liddick, said Chusovitina is a role model and an inspiration.

Chusovitina began gymnastics in 1982. In 1988, at the age of 13, she won the all-around title at the USSR National Championships in the junior division.

By 1990, Chusovitina was a vital member of the Soviet team, and was sent to compete in various international meets. She was the vault gold medalist at the 1990 Goodwill Games and nearly swept the 1990 World Sports Fair in Japan, winning the all-around and every event except the uneven bars. The following year she won the floor exercise at the 1991 World Artistic Gymnastics Championships and placed second on the vault. In 1992 Chusovitina competed at the Olympics with the Unified Team, shared in the team gold medal and placed seventh in the floor final. She also won her second World Championships vault medal, a bronze.
