USS Trieste (NCC-37124) was a Merced-class Federation starship in operation during the mid-24th century.
The Trieste was a former posting of Lieutenant Commander Data. During his tour of duty aboard, the Trieste passed through an unstable wormhole. (TNG: "Clues")
The Trieste was the nearest starship to Starbase 74 in 2364, when the Enterprise-D was hijacked from that facility. It was suggested that the Trieste might be able to intercept the Enterprise. Unfortunately, the Trieste was determined to be too small and too slow to render assistance, on top of the fact that it was sixty-six hours away at the time. (TNG: "11001001")
In 2368, the Trieste formed part of the blockade taskforce dispatched by Jean-Luc Picard along the Klingon-Romulan border during the Klingon Civil War. (TNG: "Redemption, Part II")
- Named after the Italian harbor city, and the bathyscaphe used in Auguste Piccard's dive into the Marianas Trench.
