Blow Job is a silent film directed by Andy Warhol. It depicts the face of an uncredited DeVeren Bookwalter as he apparently receives fellatio from an unseen partner. While shot at 24 frames per second, Warhol specified that it should be projected at 16 frames per second, slowing it down by a third.

Despite the salacious title, the film shows only the expression on the young man's face; the implied sexual act itself is not seen. Whether it is a male or a female performing the act is not stated, and the viewer must assume that fellatio is occurring. The salaciousness has also been speculated to be entirely in the title with no fellatio actually being performed.
