Bec Rawlings (born 11 February 1989) is an Australian mixed martial artist and bare-knuckle boxer, who currently competes in the flyweight division.

Rawlings was raised in Tasmania, and frequently played sports such as basketball, gymnastics and athletics during her pre-teens.

[4] As a teenager, however, Rawlings experienced rapid weight gain and suffered from a lack of motivation before turning to the sport of mixed martial arts as a way to battle her issues in 2010.

[4] Known for her aggressive fighting style, Rawlings began her mixed martial arts journey in Launceston, Tasmania in 2010 before relocating to Brisbane, Australia to further her opportunities and experience in early 2011.

[5] Bouncing back and publicly rallying within the Australian MMA circuit for more fight opportunities at her suited weight class, Rawlings secured consecutive submission victories over Sarah Morrison (at BRACE 14) and Daniela Marjanovic (at Australian Fighting Championship 3).

This streak, coupled with a noticeable lack of legitimate Australian opponents for Rawlings, caught North America's Invicta Fighting Championships' attention in late 2012.

[6] In November 2012, Rawlings signed a three-fight contract with Invicta Fighting Championships to compete in their strawweight division.

She was originally scheduled to fight Joanne Calderwood on the undercard of Invicta FC 4: Esparza vs. Gadelha on 5 January 2013, but an injury to Cláudia Gadelha resulted in Rawlings being pushed up to an Invicta FC Strawweight Championship fight in the main event against Carla Esparza.

[31] She lost the fight via KO in the second round after being dropped by a flying head kick and a flurry of follow up punches.

[35] Rawlings was again expected to face Joanne Calderwood in flyweight bout at UFC Fight Night: Werdum vs. Tybura on 19 November 2017.

Shortly after her victory, the Bare Knuckle Boxing Hall of Fame awarded her the inaugural Police Gazette Women's Featherweight World Championship.

[50] On 2 February 2019 at the BKFC 4 in Cancun, Mexico, Bec Rawlings beat Cecilia Flores by unanimous decision.

Rawlings faced Taylor Starling on 25 January 2025 at BKFC Knucklemania V.[57] She won the fight by unanimous decision.

[58] Rawlings made her professional boxing debut against Natasha Kurene on 3 December 2022, under Star Power promotion.

[61] As of January 2014 Bec started going by her maiden name (Rawlings) and was in a relationship with fellow Australian mixed martial artist Ben Wall.
