"The Chase" is the 146th episode of the science fiction television series Star Trek: The Next Generation. In this episode, four competing expeditions -- Federation, Klingon, Cardassian, and Romulan -- attempt to solve a genetic puzzle that proves to be the key to why Star Trek's version of the galaxy contains so many humanoid life forms. They are similar in appearance to the "generic humanoid" form taken by Odo and his shape shifting race from Star Trek: Deep Space Nine.

The Chase is a serial in the British science fiction television series Doctor Who, which was first broadcast in six weekly parts from May 22 to June 26, 1965. The story is set on multiple locations including the Marie Celeste, the Empire State Building, and the planet Aridius. The serial marks the last appearance of William Russell and Jacqueline Hill as companions Ian Chesterton and Barbara Wright and the introduction of Peter Purves as new companion Steven Taylor.

The Chase is a 1946 movie, shot in black and white, directed by Arthur Ripley. The convoluted screenplay (adapted by Philip Yordan) is based on the Cornell Woolrich novel The Black Path of Fear.
