Meridian House is a historic mansion in Washington, D.C., located in the Meridian Hill neighborhood of Northwest D.C.. It was designed by American architect John Russell Pope and built in 1920 for Ambassador Irwin B. Laughlin, who filled it with his extensive collection of French paintings and Oriental porcelain. It stayed in the Laughlin family until 1960, when it was purchased by the non-profit Meridian International Center.
