Mary Spencer (born December 12, 1984) is a Canadian professional boxer who has held the WBA female super-welterweight title since September 2024. As an amateur she won three World Championships and a Pan American Games gold medal.
Spencer competed in multiple sports as a child including basketball, volleyball, soccer and track and field. [1] She began serious boxing training in 2002, eventually linking up with coach Charlie Stewart at the Windsor Amateur Boxing Club. [2]
Spencer won three World Championships taking the 66 kg title in 2005 and 2008 then the 75 kg crown in 2010. [3] [4] She also won a gold medal at the 2011 Pan-American Games in Mexico defeating Yenebier Guillen of the Dominican Republic in the 75 kg final. [5]
Considered a medal favourite at the London 2012 Summer Olympics, which were the first Games to include women's boxing, [6] Spencer received a bye into the quarter-finals where she lost to China's Li Jinzi who she had beaten in the world championship final two years earlier. [7]
Having turned professional after the Olympics, Spencer was undefeated in her first six pro-fights and in her seventh contest won the WBA female International and WBC female Silver super-welterweight titles with a first-round stoppage success over the previously unbeaten Mexican boxer Cynthia Lozano in Montreal, Canada, on 9 September 2022. [8] [9]
Next she took on Belgian boxer Femke Hermans for the vacant IBO female super-welterweight World title losing the bout in Shawnigan, Quebec, Canada, on 16 December 2022 by unanimous decision. [10]
A rematch was held on 11 October 2023, in Montreal, Canada, with the IBO belt and the vacant IBF female super-welterweight title up for grabs. Once again Hermans got the victory, this time by majority decision. [11]
Spencer snapped her losing streak with a win over Sonya Dreiling on 25 January 2024, taking victory via retirement when her American opponent failed to answer the bell at the start of round two. [12] [13]
On 5 September 2024 at Montreal Casino, Quebec, Canada, Spencer defeated Naomi Mannes by unanimous decision to win the interim WBA super-welterweight title. [14] [15]
Spencer was elevated to a full champion after Terri Harper vacated the title. [16] She made her first defense against Ogleidis Suárez back at Montreal Casino on 10 April 2025, winning by unanimous decision. [17] [18]
Spencer is scheduled to defend her WBA super welterweight title against Mikaela Mayer in Montreal, Canada on October 30, 2025. [19] [20] [21]
Spencer was born in Wiarton, Ontario, Canada, and is a member of the Chippewas of Nawash Unceded First Nation formerly known as the Cape Croker First Nation. [2] She was an Indspire Award recipient in the sports category in 2014 and was awarded the 2019 Randy Starkman Award by the Canadian Olympic Committee. [22] In January 2024, Spencer joined the Boxing Ontario board of directors. [23]
