Izmaylovo Estate (Russian: Усадьба Измайлово) was a country residence of the House of Romanov built in the reign of Alexis I of Russia. Originally located 7 kilometres east of Moscow's city limits, it became part of the expanding city in the 20th century. Its territory spanned 10 to 15 square kilometres of the Serebryanka river valley and corresponds, roughly, to present-day Izmaylovo Forest, Terletsky Forest (south-east) and the Cherkizovo market (north-west) territories between the inner ring of the Moscow Railroad and the MKAD beltway.
