Birth control is a regimen of one or more extra actions, devices, or medications followed in order to deliberately prevent or reduce the likelihood of a woman becoming pregnant. Methods and intentions typically termed birth control may be considered a pivotal ingredient to family planning. Mechanisms which are intended to reduce the likelihood of the fertilization of an ovum by a spermatozoon may more specifically be referred to as contraception. Contraception differs from abortion in that the former prevents fertilization, whereas abortion terminates an already established pregnancy. Methods of birth control which may prevent the implantation of an embryo if fertilization occurs are controversially described by either term — see morning-after pill for a more complete discussion.

Birth control is a controversial political and ethical issue in many cultures and religions, and although it is generally less controversial than abortion specifically, it is still opposed by many. There are various degrees of opposition, including those who oppose all forms of birth control short of sexual abstinence; those who oppose forms of birth control they deem "unnatural", while allowing natural family planning; and those who support most forms of birth control that prevent fertilization, but oppose any method of birth control which prevents a fertilized embryo from attaching to the uterus and initiating a pregnancy.
