Vanes Norikovich Martirosyan (/ˈvɑːnɛs/ Armenian: Վանես Մարտիրոսյան; born May 1, 1986) is an Armenian-American former professional boxer who competed from 2005 to 2018.

Vanes' father, Norik Martirosyan, was an amateur boxer in Armenia who worked for an industrial company and was also in the army.

[2] Martirosyan was taken out of junior high school by his father and became home-schooled once it had become clear that he needed to keep his son's fighting confined to the ring.

Notable boxers Martirosyan defeated as an amateur include Austin Trout (three times), Andre Berto, and Timothy Bradley.

[7] He is also co-managed by Shelly Finkel, who also manages and advises world champions such as Wladimir and Vitali Klitschko, Evander Holyfield, Manny Pacquiao, among others.

[10] Martirosyan subsequently scored a shutout unanimous decision over Clarence Taylor,[11] and also recorded wins against Billy Lyell (who would later topple previously unbeaten John Duddy), Harrison Cuello, Andrey Tsurkan and Willie Lee.

[12] Martirosyan was scheduled to make his HBO debut on June 5, 2010 in Yankee Stadium on the Miguel Cotto vs. Yuri Foreman undercard.

[16] Martirosyan fought veteran Troy Lowry on the Julio César Chávez, Jr. vs. Marco Antonio Rubio undercard.

[17] On November 9, 2013 Martirosyan was defeated on a split decision by Demetrius Andrade who on that day became a winner of the World Boxing Organization title.

[18] On March 21, 2014 he appeared on ESPN's Goossen Tutor Promotions, defeating Mario Antonio Lozano via unanimous decision after 10 rounds in a fight for the vacant WBO Inter-Continental light middleweight title.

[19] On February 17, 2015 Showtime announced that Martirosyan would appear on a doubleheader at the Palms Casino Resort in Las Vegas on March 28 against Jermell Charlo (25-0).

[24] On May 5, 2018 Martirosyan fought unified Middleweight champion Gennady Golovkin at the StubHub Center in Carson, California after he was chosen as the late replacement for Canelo Álvarez when Canelo withdrew from the much anticipated Cinco De Mayo rematch in the wake of his failed drug tests for Clenbuterol.

With only three weeks of preparation for the bout and almost two years since his last professional fight, Martirosyan faced long odds against the undefeated middleweight champion.
