Viacheslava of Novgorod (Russian: Вячеслава новгородская, Polish: Wierzchosława Nowogrodzka; b. ca. 1125 – d. 15 March by 1162?), was a Kievan Rus' princess member of the House of Rurik and by marriage Duchess of Masovia and Kuyavia and High Duchess of Poland since 1146.

She was the daughter of St. Vsevolod, Prince of Novgorod and Pskov by his wife, a daughter of Svyatoslav Davidovich, Prince of Chernigov.

Nothing is known about Viacheslava's first years; she was one of three children and their only daughter. She had two brothers, Ivan and Vladimir (who was confused in several sources as husband of Princess Richeza of Poland). Both died unmarried and apparently childless.

Around 1137 she was married with Bolesław, son of the Polish Duke Bolesław III Wrymouth. The wedding was probably orchestrated by Bolesław's mother Salomea of Berg, who wanted to secure a Russian alliance against her stepson, the later Władysław II the Exile. On 11 February 1138 Prince Vsevolod died and on 28 October of that year Duke Bolesław III also died, leaving in his will his domains divided between his sons. Prince Bolesław received the Masovian state as Bolesław IV, Duke of Masovia and Kuyavia, and Viacheslava became in the Duchess consort.
