Jānis Lipke was a Latvian rescuer of Jews in Riga during World War II.
Lipke, a dock worker in the port of Riga, was determined to help save Latvian Jews from capture by the Nazis after witnessing actions against them in the streets. He retrained in order to become a contractor for the Luftwaffe, and then used his position to smuggle Jewish workers out of the Riga ghetto and camps in and around Riga, whom he concealed with the aid of his wife Johanna until the arrival of the Red Army in October 1944. The Lipkes and their various helpers saved forty people in this way, one fifth of the approximately 200 Jews who survived the war in Latvia.
Yad Vashem recognized him and his wife as Righteous Gentiles on June 28, 1966.
