Sivtsev Vrazhek is a radial lane in the Central Administrative Okrug of Moscow; it forms the boundary between Arbat and Khamovniki municipal districts.

During the 17th century the area was fragmented into four slobodas of different trades employed by the Court: from east to west, these were icon painters, horse grooms, carpenters and mint workers.

Notable 19th-century residents included Peter Kropotkin, Alexander Herzen, count Fyodor Tolstoy "The American", Sergey Aksakov; general Yermolov owned the building on the corner of Boulevard Ring but himself lived on Prechistenka Street.

[3] In 1863 Leo Tolstoy wrote in his diary that he dreamed of his own place in Sivtsev Vrazhek where he could spend the winter months in country style.

The only building added in the interbellum period was a 1932 experimental apartment block designed by Dmitry Lebedev and Nikolai Ladovsky, notable for its combination of segments linked at 120° angle.
