Cristina Bontaş (later Tăntaru, born December 5, 1973) is a Romanian former artistic gymnast, who competed in international events between 1987 and 1993.

The 1988 Junior Friendship Tournament (Druzhba) was another especially successful meet: she won gold for floor, bronze for balance beam and vault and finished fourth in the all around event.

Bontaş was the surprise top Romanian gymnast at the 1989 World Championships, finishing in fourth place in the all around event ahead of the great Daniela Silivaş and just behind the trio of Soviet medalists (Boginskaya, Laschenova and Strazheva).

[8] In 1990 she won silver medal on vault at the European Championships in Athens, Greece and placed seventh in the floor and uneven bars events.

[10][11] Her performance on the floor exercise based on a musical background of well-known American songs (e.g., "The Star-Spangled Banner" (USA anthem), "Oh Susanna", "When Johnny Comes Marching Home Again", "Yankee Doodle" and "Deep in the Heart of Texas") energized the crowds.

[16] She won silver with the team, tied for the bronze medal on floor exercise with Tatiana Gutsu and Shannon Miller, and placed fourth in the all-around and beam finals.

She went back to Romania in 1998 to marry, returning to Canada without husband Gabi Tăntaru while they waited for immigration papers.
