Anton Sergeyevich Belov (; born 29 July 1986) is a Russian professional ice hockey defenceman. He is currently an unrestricted free agent who most recently played with Avangard Omsk in the Kontinental Hockey League (KHL). He has previously played with CSKA Moscow, SKA Saint Petersburg, Dynamo Moscow and played one season in the National Hockey League (NHL) with the Edmonton Oilers.
In 2013, Belov decided he wanted to ply his trade in the NHL. On 30 May 2013, the Edmonton Oilers announced that they had signed Belov to a one-year entry-level contract. Belov made the team roster to begin the 2013–14 season. On 10 January 2014, Belov scored his first NHL goal against Jeff Zatkoff of the Pittsburgh Penguins. Despite his status as a top defenceman in the KHL, Belov was used in a depth role with the Oilers and finished the year with 7 points in 57 games.
On 16 April 2014, as an approaching free agent, Belov signed a lucrative four-year contract to return to the Russian KHL with SKA St. Petersburg.
Following a lone season with Dynamo Moscow in 2021–22, Belov returned to his former club, Avangard Omsk, as a free agent in signing a one-year contract on 3 May 2022.
