Gretchen Magbanua Abaniel (born November 4, 1985) is a Filipino professional boxer.

Abaniel's father thought she should learn martial arts like karate and she later grew interested in boxing, joining the national team to start her amateur career.

[2] Abaniel, a resident of Puerto Princesa, has been supported by her town's mayor, Edward Hagedorn, throughout her career, even when becoming part of the Philippine national team in 2003 due to inadequate support from the Philippine Sports Commission.

[3] Abaniel won her first world title match against Thailand's Nongbua Lookpraiaree after a tenth-round unanimous decision allowed her to capture the vacant Women's International Boxing Association World minimumweight title.

[6] She was also a guest on a morning news-talk program called GMK conceptualized by Daniel Razon.
