Principality of Odoyev

The Principality of Odoyev (Russian: Одоевское княжество) was a late medieval Russian principality. It was one of the Upper Oka Principalities and it existed from 1376 to 1573. The town of Odoyev was the center of the principality.

From 1407, it was under the political authority of the Grand Duchy of Lithuania. During the 15th century, it disintegrated into a number of appanages belonging to the princes Vorotynsky and Odoyevsky. By the end of the century, it had passed to the Russian state, and the appanage princes finally lost their independence in 1573.
