Sambir (Ukrainian: Самбір, Polish: Sambor) is a city in the Lviv Oblast, Ukraine. Serving as the administrative center of the Sambir Raion (district), the city itself is also designated as a separate raion within the oblast. It is located at around 49°31′0″N 23°12′10″E / 49.516667°N 23.20278°E / 49.516667; 23.20278, close to the border with Poland.

The settlement called Pohonych was first mentioned in the 13th century, when it was destroyed by the Tatars. The inhabitants founded a new village, called New Sambir, about two kilometres from the old place. On 13 December 1390, the village was granted the Magdeburg rights, and was then owned by voivode Spytek of Melsztyn. On 5 June 1419 Polish King Władysław Jagiełło built there a wooden castle. In 1498, the city was destroyed by the Tatars, and because of that, King Jan I Olbracht released it from taxes. In 1637, the city partly burnt down, together with a local church. Famous Ukrainian cossacks - hetman Petro Konashevych-Sahaidachny and Yuriy Kulchytsky were born 7 km (4.35 mi) away from the city - in the village of Kulchytsi. Petro Sagaydachnyi played a major role in helping the Polish-Lithuanian Commonwealth win battle of Khotyn (1621), and led a large Cossack regiment in the war with Moscow.
