The Starfleet ship recognition protocol was a Starfleet protocol for recognizing friend and foe ships.

In 2369, after receiving a false alarm distress call from the New Berlin Colony after the colony misidentified a Ferengi trading ship for a Borg ship, the USS Enterprise-D transmitted another copy of Starfleet ship recognition protocols with a suggestion that the colonists read it this time.
