Semyonovskoye-Otrada, Noble estate in Semyonovskoe village, Russia.

Semyonovskoye-Otrada is an estate on the Lopasnya river in Semyonovskoye, Stupinsky district, Moscow Oblast. Its two-storey Catherine-era manor house stands in ruins: red brick walls with white pilasters and cornices, a portico of four weathered white columns under an arched pediment, and large arched windows with iron grilles. A landscape park once surrounded it.

The lands were granted to Aleksey Orlov in 1773; he passed part to his brother Vladimir, who retired in 1774 and began building the estate that year. The house is attributed to Karl Blank, built 1775–1779 under serf architects Babakin and Tsukanov. In 1832–1835 Yekaterina Novosiltseva had Domenico Gilardi build a mausoleum, and in 1848 Mikhail Bykovsky added two conservatories.

The estate's name, Otrada, means "consolation" or "joy". Its park held nightingales, hand-reared elk, roe deer and deer, plus garden sculpture, grottoes and pavilions; the deer were later sold because feeding them was too costly. A bronze bust of Catherine II, now lost, stood on the slope before the house with the inscription "To Catherine the Great, benefactress of the Orlov family".

The estate lies in Semyonovskoye village on the Lopasnya river, in Stupinsky district of Moscow Oblast. Since 1938 the grounds have belonged to the territory administered by the KGB and later the FSB, so the site is not freely open and entry must be arranged in advance. The ruined main house is fenced off and unsafe to enter.

The parade hall held a gallery of sculpted portraits of the Orlov brothers by Fyodor Shubin, one of only a few such sculpture galleries in Russian country estates, alongside those at Dugino, Olgovo and Yaropolets. A bronze bust of Catherine II, inscribed "To Catherine the Great, benefactress of the Orlov family", stood on the hillside before the house; it is now lost.
