Sexual penetration is the insertion of a body part or other object into a body orifice, such as the mouth, vagina or anus, as part of human sexual activity or sexual behavior in non-human animals.
The term is most commonly used in statute law in the context of proscribing certain sexual activities. Terms such as "sexual intercourse" or "carnal knowledge" are more commonly found in older statutes, while many modern criminal statutes use the term "sexual penetration" because it is a broad term encompassing (unless otherwise qualified) any form of penetrative sexual activity, including digital (i.e., the fingers) or with an object, and may involve only the most minimal penetration. Some jurisdictions refer to some forms of penetration as "acts of indecency", or other terminology.

Penetrative oral sex may involve penetration of the mouth by a penis (fellatio) or the use of the tongue to penetrate a vagina or vulva (cunnilingus). The tongue may also penetrate the anus during anilingus. If one or more fingers are used to penetrate an orifice, it is called fingering or digital penetration. The insertion of an object, such as a dildo, vibrator or other sex toy, into a person's genital area or anus may also be considered sexual penetration. Penetrative sex is referred to as coitus or connotative sex.

Penetrative sex crimes are generally considered more serious than non-penetrative sex crimes,[http://www.cps.gov.uk/legal/s_to_u/sentencing_manual/sexual_assult_by_penetration/ Guidelines for sentencing, UK] {{webarchive|url=https://web.archive.org/web/20131115152923/http://cps.gov.uk/legal/s_to_u/sentencing_manual/sexual_assult_by_penetration/ |date=2013-11-15 }} and sexual penetration of a child even more so. A child below the statutory age of consent cannot consent to acts involving sexual penetration. In laws, the term sexual penetration is commonly used in relation to sex with children. Unlawful sexual penetration is generally an offense irrespective of how deep the penetration was and irrespective of whether ejaculation of semen took place.
Laws may distinguish particular forms of sexual penetration as part of the offense. For example, the law in the U.S. state of Oregon provides:
{{quote|"Unlawful sexual penetration in the first degree" is a felony that occurs where the offender "penetrates the vagina, anus or penis of another with any object other than the penis or mouth of the actor", if the victim is "subjected to forcible compulsion", or is "under 12 years of age", or "is incapable of consent by reason of mental defect, mental incapacitation or physical helplessness"|[https://www.oregonlaws.org/ors/163.411 Unlawful sexual penetration in the first degree], Oregon Statutes § 163.411}}
In the United Kingdom, sexually penetrating a relative is an offense.[http://www.legislation.gov.uk/ukpga/2003/42/part/1/crossheading/sex-with-an-adult-relative Sexual Offences Act 2003] retrieved 24 February 2012
Various forms of penetration have at times been considered obscene and been prohibited. Works containing such penetrations may be considered pornography.{{citation needed|date=July 2013}}
