Trieste, slovenska och kroatiska: Trst, samt tyska Triest är en stad och huvudort i provinsen Trieste i regionen Friuli-Venezia Giulia i nordöstra Italien, nära gränsen till Slovenien.
T was one of the oldest parts of the Habsburg Monarchy. In the 19th century, it was the most important port of one of the Great Powers of Europe. As a prosperous seaport in the Mediterranean region, T became the fourth largest city of the Austro-Hungarian Empire (after Vienna, Budapest, and Prague). In the fin-de-siecle period, it emerged as an important hub for literature and music. It underwent an economic revival during the 1930s, and the city was an important spot in the struggle between the Eastern and Western blocs after the Second World War. Today, the city is in one of the richest regions of Italy, and has been a great centre for shipping, through its port (Port of Trieste), shipbuilding and financial services.
In 2012, LonelyPlanet.com listed the city as the world’s most underrated travel destination.
