Bryachislav Vasilkovich of Vitebsk

Bryachislav Vasilkovich (died after 1186) was a Polotsk-branch Rurikid who held Iziaslavl and twice ruled Vitebsk. Around 1159 Prince Rogvolod Borisovich of Polotsk granted him Iziaslavl, which he held with his brother Volodsha, until the Glebovichi princes of Minsk captured the brothers; Rogvolod freed Bryachislav in 1160.

In 1162 he joined the Polotsk princes' campaign to Slutsk against Dorogobuzh, and in 1180, ruling Vitebsk, he fought at Drutsk for the Kiev prince Svyatoslav Vsevolodovich.
