The Moldova–Ukraine border, the official border between Republic of Moldova and Ukraine, was established after the dissolution of the Soviet Union. The length of the inland border is 1,222 kilometres (759 mi), of which 267 kilometres (166 mi) is fluvial (i.e., along rivers) and 955 kilometres (593 mi) is land border. About 454 kilometres (282 mi) of it constitutes the de facto border between Ukraine and the unrecognized breakaway republic of Transnistria.
The border runs from the northern Romania-Moldova-Ukraine tripoint in the northwest of the country, 4 kilometres (2.5 mi), from the Ukrainian village and border crossing of Mamalyha, Ukraine to Criva, Briceni, Moldova. It runs east until the city and border crossing of Mohyliv-Podilskyi, where it turns southeast and enters the channel of the river of Dniester. By the village of Nimereuca the territory of Transnistria begins, which ends by Purcari. Several kilometers further it turns west. By Basarabeasca District it turns south and runs until the southern Romania-Moldova-Ukraine tripoint near Galați, Romania and Reni, Ukraine, by the Danube.
