Stabilimento Tecnico Triestino (STT) ("Technical Establishment of Trieste") was a private shipbuilding company based in Trieste from the mid-19th to early 20th century, and the most important naval shipbuilding firm of the Austro-Hungarian Empire.

After World War I, Trieste was annexed by Italy and the firm built naval and commercial vessels for its new host country. STT was merged with another Italian shipbuilding firm, Cantiere Navale Triestino, in 1929 to form Cantieri Riuniti dell'Adriatico (CRDA). As CRDA Trieste, its shipyards remained active well into the postwar period, becoming part of the Fincantieri group in 1984.
