Marie Louise "Masha" Yovanovitch (born November 11, 1958) is an American diplomat and member of the senior ranks of the United States Foreign Service. She served in multiple State Department posts, including Senior Advisor to the Under Secretary of State for Political Affairs (2004–2005); U.S. Ambassador to Kyrgyzstan (2005–2008); U.S. Ambassador to Armenia (2008–2011); Principal Deputy Assistant Secretary for the Bureau of European and Eurasian Affairs (2012–2013); and Ambassador to Ukraine (2016–2019). Yovanovitch is a diplomat in residence at the Institute for the Study of Diplomacy at Georgetown University. On January 31, 2020 it was reported that she has retired from the State Department. While ambassador to Ukraine, Yovanovitch was the target of a conspiracy-driven smear campaign, amplified by President Donald Trump and his allies. In May 2019, Trump abruptly recalled Yovanovitch from her post following claims by Trump surrogates that she was undermining Trump's efforts to pressure Ukraine to investigate his political rival, former vice president and 2020 U.S. presidential election candidate Joe Biden. Yovanovitch's removal preceded a July 2019 phone call by Trump in which he attempted to pressure Ukraine president Volodymyr Zelensky to investigate Biden. Following a whistleblower complaint about the phone call and attempts to cover it up, an impeachment inquiry against Trump was initiated by the House of Representatives. Yovanovitch testified in several House committee depositions in the inquiry.
