Hendrik Evert Koot (5 April 1898 – 14 February 1941) was a Dutch collaborator with the German occupying forces during World War II. A member of the WA, the paramilitary wing of the National Socialist Movement in the Netherlands (NSB), he was beaten up by members of a local knokploeg ("action group") in Amsterdam on 11 February 1941. His injuries were so severe that he died a few days later. His death was seized by the German authorities to start raids in the Jodenbuurt, the Amsterdam Jewish quarters, which in turn led to the February strike. Another element of Nazi retaliation was the installation of a Judenrat in Amsterdam.
