A self-induced abortion (also called a self-managed abortion, or sometimes a self-induced miscarriage) is an abortion performed by the pregnant woman herself, or with the help of other, non-medical assistance. Although the term includes abortions induced outside of a clinical setting with legal, sometimes over-the-counter medication, it also refers to efforts to terminate a pregnancy through alternative, potentially more dangerous methods. Such practices may present a threat to the health of women.

Self-induced (or self-managed) abortion is often attempted during the beginning of pregnancy (the first eight weeks from the last menstrual period). In recent years, significant reductions in maternal death and injury resulting from self-induced abortions have been attributed to the increasing availability of misoprostol (known commercially as "Cytotec"). This medication is a synthetic prostaglandin E1 that is inexpensive, widely available, and has multiple uses, including the treatment of post-partum hemorrhage, stomach ulcers, cervical preparation and induction of labor. The World Health Organization (WHO) has endorsed two regimens for abortion up to 12 weeks of pregnancy using misoprostol: a standardized regimen of mifepristone and misoprostol and a regimen of misoprostol alone. The regimen with misoprostol alone has been shown to be up to 83% effective in terminating a pregnancy but is more effective combined with mifepristone.
