Paraphilia (also known as sexual perversion and sexual deviation) is the experience of intense sexual arousal to atypical objects, fetishes, situations, fantasies, behaviors, or individuals. No consensus has been found for any precise border between unusual sexual interests and paraphilic ones. There is debate over which, if any, of the paraphilias should be listed in diagnostic manuals, such as the Diagnostic and Statistical Manual of Mental Disorders (DSM) or the International Classification of Diseases (ICD).

The number and taxonomy of paraphilias is under debate; one source lists as many as 549 types of paraphilias. The DSM-5 has specific listings for eight paraphilic disorders. Several sub-classifications of the paraphilias have been proposed, and some argue that a fully dimensional, spectrum or complaint-oriented approach would better reflect the evidence.

Many terms have been used to describe atypical sexual interests, and there remains debate regarding technical accuracy and perceptions of stigma. Sexologist John Money popularized the term paraphilia as a non-pejorative designation for unusual sexual interests. Money described paraphilia as "a sexuoerotic embellishment of, or alternative to the official, ideological norm." Psychiatrist Glen Gabbard writes that despite efforts by Stekel and Money, "the term paraphilia remains pejorative in most circumstances."

Coinage of the term paraphilia (paraphilie) has been credited to Friedrich Salomon Krauss in 1903, and it entered the English language in 1913, in reference to Krauss by urologist William J. Robinson. It was used with some regularity by Wilhelm Stekel in the 1920s. The term comes from the Greek παρά (para) "beside" and φιλία (-philia) "friendship, love".
