Denis Alekseyevich Petrov (Russian: Денис Алексеевич Петров; born 3 March 1968) is a Russian former pair skater who competed for the Soviet Union, the Commonwealth of Independent States, and the Unified Team.

In 1992, they won the Soviet Nationals over the teams of Evgenia Shishkova / Vadim Naumov and Marina Eltsova / Andrei Bushkov (Bechke/Petrov's training partners and chief rivals, Natalia Mishkutenok / Artur Dmitriev, missed the Nationals but qualified for the Olympics as they were the reigning World Champions).

Scott Hamilton once joked that Petrov is such a strong and consistent skater that he only falls once a year.

Hamilton has also said that the Stars on Ice cast nicknamed him "Conan" for getting bigger after every tour, while Kristi Yamaguchi has said that he is also nicknamed "the human crane" because he has lifted just about everybody in the show, including performing a two-hand detroiter with Scott Hamilton in the 2000–01 group number, "Tunnel Vision."

Petrov and his wife work at the World Ice Arena in Shenzhen, she as the manager and he as the head coach of the skating academy.

On 8 July 2005, Petrov married Chinese figure skater Chen Lu, who he met on the 1998–99 Stars on Ice tour.
