Elena Mikhailovna Zamolodchikova (Russian: Еле́на Миха́йловна Замоло́дчикова; born September 19, 1982, in Moscow), nicknamed "Zamo", is a two-time Olympic gymnast. She was known for her risky double-twisting double-backflip on floor and was one of a handful of women to have successfully competed one. In 2015, she was inducted in the International Gymnastics Hall of Fame.

Zamolodchikova began gymnastics at the age of six. In 1999 she participated in her first major senior competition, the World Gymnastics Championships. She won the gold in vault and the bronze in the all-around.

Just days before the 2000 European Championships in Paris, her father died as a result of radiation exposure from the Chernobyl accident. Zamolodchikova led her team to the gold medal and earned individual silvers in the all-around and vault finals and a bronze on the beam.

Zamolodchikova was selected as a member of the Russian gymnastics team at the 2000 Summer Olympics in Sydney. Although initially she did not qualify into the all-around or vault finals, she earned spots in both when Elena Produnova withdrew from the all-around and Svetlana Khorkina decided to give up her spot to Zamolodchikova. In the team competition, the Russian team was leading after the preliminary rounds, however, four Russian gymnasts made mistakes in the finals, costing them the gold. Zamolodchikova was one of the four, slipping off the beam as she took off for a Rulfova and narrowly missing her head.

After two apparatus in the all-around, Zamolodchikova was in first place with her stronger exercises still to go. However, she lost her chances of an all-around medal with a fall on the floor exercise on her simplest tumble. On a night where many gymnasts made uncharacteristic errors, she eventually finished 6th. Had she scored the same in the all-around as she did for her team finals performance, her total would have been enough to win her the gold.
