Imants Sudmalis (18 March 1916 OS, Cesis, Governorate of Livonia, Russian Empire – 25 May 1944 NS, Riga, Latvia) was a Latvian editor and Soviet communist and partisan, the Hero of the Soviet Union (awarded posthumously on October 23, 1957).
His organization of the bombing of an anti-Soviet protest in response to reports of Allied negotiations in Moscow in November 1943 discussing assigning the Baltics to the Soviet sphere has been described as an act of terrorism by researchers of the Latvian Museum of the Occupation; Soviet sources described it as an act of "disrupting a Nazi occupier-organized inflammatory anti-Soviet demonstration."
