Vladislav I (Bulgarian: Владислав I Romanian: Vladhyslao I) of the Basarab dynasty also known as Vlaicu-Vodă was a ruler of the principality of Wallachia (a part of modern-day Romania) (1364 – c. 1377). He was a vassal of the Bulgarian Emperor Ivan Alexander. In 1369 Vladislav I subdued Vidin and recognised Louis I of Hungary as his overlord in return for Severin Amlaş and Făgăraş.
