Priority 7 was a term used by Starfleet officers in the 23rd century for hostage situations on Federation worlds.

In 2287, Commander Nyota Uhura intercepted a message from Starfleet Command, sent to the USS Enterprise-A. The message stated that there was a priority 7 situation in the Neutral Zone on the planet Nimbus III, after Sybok took representatives Caithlin Dar, St. John Talbot and Korrd hostage. After confirming the message, Uhura had the Enterprise's crew rounded up from their shore leave and they soon left for Nimbus III. (Star Trek V: The Final Frontier)
