The Lothrop Mansion, also known as the Alvin Mason Lothrop House, is an historic home, located at 2001 Connecticut Avenue, Northwest, Washington, D.C., in the Kalorama Triangle neighborhood.

Until a scale-back in Russian diplomatic presence in 2017,^[2][3] the Lothrop Mansion housed offices for the Russian Trade Representative.^[4]

History

The Beaux Arts home was designed by local architects Hornblower and Marshall, for Alvin Mason Lothrop, in 1908 at a cost of $100,000.^[5]

In 1942 the Soviet government bought the building from Nathaniel Luttrell, Jr., the grandson of the original inhabitant. While originally purchased to become the USSR embassy's chancellery,^[6] it would officially house the offices of the USSR Trade Representative until the end of the Soviet era.

The Lothrop Mansion is listed on the National Register of Historic Places,^[7] and is designated as a contributing property to the Kalorama Triangle Historic District.^[8] It is currently vacant.
