Anti-abortion movements advocate against the practice of abortion, both through seeking legal bans and other means. Modern anti-abortion movements generally began as countermovements in response to the decriminalization and legalization of elective abortion in various countries.
United States 
Anti-abortion advocacy in the United States is centered around the United States pro-life movement.
In Europe, abortion has been legalized through parliamentary acts. In Western Europe this has had the effect at once of both more closely regulating the use of abortion, and at the same time mediating and reducing the impact anti-abortion campaigns have had on the law.
- In France, the first specifically anti-abortion organization, Laissez-les-vivre-SOS futures mères, was created in 1971 during the debate that was to lead to the Veil Law in 1975. Its main spokesman was the geneticist Jérôme Lejeune. Since 2005, the French anti-abortion movement has organized an annual March for Life in Paris attracting several thousand demonstrators.
- In the United Kingdom, the most prominent anti-abortion organization is the Society for the Protection of Unborn Children.
- In Spain, over one million demonstrators took part in a march in Madrid in October 2009 to protest plans by the government of José Luis Zapatero to legalize elective abortions and eliminate parental consent restrictions.
In Israel, the major anti-abortion organization is Efrat. Efrat activists primarily raise funds to relieve the "financial and social pressures" on pregnant women so that they will not terminate their pregnancies. Efrat is not known to do any other kind of activism.
