Algirdas Klimaitis (1910 in Kaunas – 29 August 1988 in Hamburg) was a Lithuanian paramilitary commander, infamous for his role in the Kaunas pogrom in June 1941. It is likely that Klimaitis was an officer in the Lithuanian Army. During the pre-war years he was editor of the tabloid (Ten Cents). His attitudes shifted to anti-communism and anti-semitism. He joined the Voldemarininkai movement.
