The T'Met was a Romulan D'deridex-class warbird that was in service with the Tal Shiar in the late 24th century. Commanded by Sub-Commander Almak, the T'Met led the force of three warbirds assigned to meet the USS Prometheus after its hijacking by Romulan operatives in 2374.

Shortly after, the T'Met engaged the Starfleet forces assigned to retrieve the Prometheus. (VOY: "Message in a Bottle")

The Starships RPG sourcebook uses the spelling "Temet" and gives its registry as I.R.C. 1964.
According to the Star Trek: Star Charts (p. 66) and the Stellar Cartography: The Starfleet Reference Library ("Stellar Cartography", pp. 32-33, "Federation Historical Highlights, 2161-2385"), there was a system named T'Met, which might be the possible origin for the name of this starship, in the Beta Quadrant. The system's primary was a F-class star. According to a map of the Romulan Empire – prepared by the Stellar Archivist Lsel Essik, from the Romulan Master Data Catalog, in 2366 – T'Met was identified as a Romulan system.
