Abramavičiai Palace (Polish: pałac Abramowiczów) is a building in Vilnius Old Town, Rotušė square. Currently it is owned by Vilnius Juozas Tallat-Kelpša conservatory.

Representative of the Abramowicz family, Andrzej, a Lithuanian writer and Castellan of Brest-Litovsk, purchased a property by the Vilnius market square in 1749, which included two tenement houses. It was inherited by his brother Jerzy, who passed away in 1767. His widow, Marcjanna née Dernałowicz, undertook the construction of a palace, demolishing the existing buildings and commencing the new palace's construction in 1783.^[1][2]

Architect Augustyn Kossakowski designed a two-story palace featuring an internal courtyard with a centrally aligned entrance gate. Between 1801 and 1806, Mikołaj Abramowicz initiated modernization efforts, focusing primarily on the palace's interiors, based on a design by Wawrzyniec Gucewicz.^[3] ​In 1814, Mikołaj Abramowicz sold the palace to Antoni Wańkowicz.^[4]

In 1844 the palace became the property of the Orthodox consistory clergy. In 1853-1860 it was rebuilt under the direction of Tomasz Tyszecki and connected with St. Casimir's Church, then an Orthodox church.^[2] In 1914-15 the palace was the seat of Vilnius Orthodox Archbishop Tikhon (Vasily Belavin). In the interwar period, the building belonged to the Jesuit Order.^[2] After World War II it was Juozas Tallat-Kelpša High School of Music, which later was transformed into conservatory.
