"Where Silence Has Lease" is the second episode of the second season of the American science fiction television series Star Trek: The Next Generation, the 28th episode overall. It was originally released on November 28, 1988 in broadcast syndication. Directed by Winrich Kolbe, it was written by Jack B. Sowards.

Set in the 24th century, the series follows the adventures of the crew of the Federation starship Enterprise. In this episode, the Enterprise becomes enveloped by a void in space where the crew are tested by a powerful alien presence.

While on a charting mission, the Federation starship Enterprise, under the command of Captain Jean-Luc Picard, discovers a patch of pure blackness in space; probes launched into the area simply disappear. As they study it further, the patch expands and soon envelops the Enterprise, leaving them in a black void with sensors reporting complete nothingness outside. Picard orders the ship on a return course, but they find that they cannot escape; they leave a stationary beacon behind them, only to have it reappear ahead of them again.

A Romulan Warbird suddenly decloaks in front of the ship and attacks, and Picard orders the crew to return fire; they destroy the Warbird, but Picard is suspicious of how easily. The crew then detect what appears to be their sister ship, the USS Yamato, approaching, but it does not respond to hails. Commander Riker and Lt. Worf beam over to search the ship, where they find it empty, with inconsistencies in its construction, including more seemingly impossible physical loops. The Enterprise then detects an exit from the darkness, but cannot lock onto the away team to retrieve them before the opening disappears. The Yamato begins to fade away, but the Enterprise is able to beam Riker and Worf back just in time. More openings appear in the blackness, each closing as soon as the Enterprise approaches them. Picard realizes that they are being manipulated, and orders a full-stop.
