The aircraft, which was carrying 65 passengers and six members of flight crew, disappeared from radar just minutes after leaving Domodedovo Airport on Sunday.
Wreckage was found in the Ramenskoye area about 25 miles from the airport.
All those on board have been confirmed dead, Russia’s transport minister has said.
Reports said the plane was an An-148, a regional jet belonging to Saratov Airlines, which had been travelling to the city of Orsk, near to the Kazakhstan border.
Flightradar24 tweeted that the aircraft departed at 11.22am local time and began descending just five minutes later, losing signal around 20 miles south-east of the airport.
