A person who supports or is in favor of terminating pregnancies: Many proabortionists maintain that terminating a woman's pregnancy, although not a preferred family planning method, has always been used by women to gain control over their pre-birth conditions.

According to one view of proabortionists, women must have a safe and legal access to stopping their pregnancies because without this availability, women may use unsafe and illegal procedures that can result in serious injuries or death.
