Jupiter Outpost 92 was an outpost located in close vicinity of Jupiter.

In 2367, this outpost was the first to report visual contact with a Borg cube after it had dropped out of warp and entered the Terran system. (TNG: "The Best of Both Worlds, Part II")

This outpost was only mentioned in dialogue.
According to the Star Trek Encyclopedia (4th ed., vol. 1, p. 394), "In an early version of the script for "The Best of Both Worlds, Part II," the story was still considered to be so confidential that each copy of the script was secretly numbered. The number of the Jupiter Outpost (in this case, 92) was different in each copy of the early draft script, so that if unauthorized copies were made, it would be possible to trace whose copy it came from."
