Andrey Vasilievich Kvasov (1720–1770) was a notable baroque architect who worked in Russia and Ukraine. Very little is known about his life, and its dates are still uncertain.

In 1741, Kvasov helped Mikhail Zemtsov to prepare coronation celebrations in Moscow. Two years later, he was entrusted with interior decoration of the Catherine Palace, which resulted in the and other celebrated rooms.

Simultaneously, he was commissioned by the hetman Kirill Razumovsky to design the residences and churches in Baturin, Glukhov, and Koselets. In 1770, he was made Principal Architect of Little Russia. The cathedral in Kozelets and the ruined palace in Baturin are among a handful of his Ukrainian buildings which still stand, although little remains of their original designs and decor.

Kvasov is also credited with devising the general layout of Kazan (1766), Tver (1767), Astrakhan (1768), Kharkov (1768), and the Admiralty part of St Petersburg.
