A cum shot is the depiction of human ejaculation, especially onto another person. The term is usually applied to depictions occurring in pornographic films, photographs, and magazines. Unlike ejaculation in non-pornographic sex, cum shots typically involve ejaculation outside the receiver's body, allowing the viewer to see the ejaculation in progress. Facial cum shots (or "facials") are regularly portrayed in pornographic films and videos, often as a way to close a scene. Cum shots may also depict ejaculation onto another performer's body, such as on the genitals, buttocks, chest or tongue.

The term is typically used by the cinematographer within the narrative framework of a pornographic film, and, since the 1970s, it has become a leitmotif of the hardcore genre. Two exceptions are softcore pornography, in which penetration is not explicitly shown, and "couples erotica", which may involve penetration but is typically filmed in a more discreet manner intended to be romantic or educational rather than graphic. Softcore pornography that does not contain ejaculation sequences is produced both to respond to a demand by some consumers for less-explicit pornographic material and to comply with government regulations or cable company rules that may disallow depictions of ejaculation. Cum shots typically do not appear in "girl-girl" scenes (female ejaculation scenes exist, but are relatively uncommon); orgasm is instead implied by utterances, cinematic conventions, or body movement.

Cum shots have become the object of fetish genres like bukkake, in which the cum shot replaces the sex act completely.
