Ants Antson (11 November 1938 – 31 October 2015) was an Estonian speed skater who competed for the Soviet Union.

Ants Antson trained at the Kalev Voluntary Sports Society. Coached by former World, Olympic, and European Champion Boris Shilkov, Antson had his best year in 1964, when he became European Allround Champion, became Olympic Champion on the 1500 m at the 1964 Winter Olympics in Innsbruck, and set a new world record on the 3000 m. For his achievements that year, he received the Oscar Mathisen Award.

The two gold medals Antson won in 1964 turned out to be his only international medals, although he did win some national medals at the Soviet Allround Championships – gold in 1967, silver in 1965 and 1968, and bronze in 1966. He participated in the 1500 m at the 1968 Winter Olympics in Grenoble, but despite skating a new personal record, he finished only twelfth.

He retired shortly after the 1968 Games and worked as a sports official, first in the Soviet Estonian Committee for Physical Culture and Sports, and later with the Estonian Olympic Committee. At the 1992 Winter Olympics he became the first flag bearer for Estonia after it became independent from the Soviet Union.

Antson has an Adelskalender score of 176.465 points. His highest ranking on the Adelskalender was a fourth place.
