This article classifies types of rape by the sex of both the rapist and the victim. The scope of the article includes both rape and sexual violence more generally.

Since only a small percentage of acts of sexual violence are brought to the attention of the authorities, it is impossible to compile accurate statistics. There are nevertheless statistical estimates published by some official bodies. The U.S. Bureau of Justice Statistics (1999) estimated that 91% of United States rape victims were female and 9% were male, with 99% of the offenders being male and 1% of the offenders being female.^{[citation needed]} Several studies argue that male-male and female-female prison rape are quite common and may be the least reported form of rape.

In a 2000 research article from the Home Office, in England and Wales, around 1 in 20 women (5%) said that they had been raped at some point in their life from the age of 16 beyond.

In 2011 the US Centers for Disease Control found that "nearly 20% of all women" suffered rape or attempted rape sometime in their life. More than a third of the victims were raped before the age of 18.

Rape is a type of sexual assault usually involving sexual intercourse, which is initiated by one or more persons against another person without that person's consent. A person who commits an act of rape is known as a rapist. The act may be carried out by physical force, coercion, abuse of authority or with a person who is incapable of valid consent. The term is most often defined in criminal law.

Internationally, the incidence of rapes recorded by the police during 2008 varied between 0.1 in Egypt per 100,000 people and 91.6 per 100,000 people in Lesotho with 4.9 per 100,000 people in Lithuania as the median. According to the American Medical Association (1995), sexual violence, and rape in particular, is considered the most under-reported violent crime. The rate of reporting, prosecution and convictions for rape varies considerably in different jurisdictions. The U.S. Bureau of Justice Statistics (1999) estimated that 91% of U.S. rape victims are female and 9% are male, with 99% of the offenders being male. Rape by strangers is usually less common than rape by persons the victim knows, and several studies argue that male-male and female-female prison rape are quite common and may be the least reported forms of rape.
