"All Good Things..." is the series finale of the syndicated American science fiction television series Star Trek: The Next Generation. It comprises the 25th and 26th episodes of the seventh season and is the 177th and 178th episodes of the series overall. It aired on May 23, 1994. The title is derived from the expression "All good things must come to an end", a phrase used by the character Q during the episode itself.

Set in the 24th century, the series follows the adventures of the Starfleet crew of the Federation starship Enterprise-D. The plot involves Captain Jean-Luc Picard jumping through time and the formation of an anomaly that defies causality, the whole situation being a test that allows Picard to demonstrate human potential to the Q Continuum by making an intuitive leap of faith to understand the cause of, and how to eliminate, the anomaly before it destroys humanity.

The finale received universal acclaim, and marked the transition of the cast to films featuring the show's cast and settings, as well as passing the television audience to Star Trek spin-offs based on similar settings to The Next Generation.
