Antti Isotalo (13 January 1895 – 17 March 1964) was a Finnish Jäger lieutenant, military recruiter, farmer and activist. He served in the German Empire's battalion of Finnish volunteers on the Eastern Front of World War I and briefly in the Finnish Civil War (1918) on the Whites' side. He repeatedly evaded capture by authorities while recruiting men for the battalion in 1915 and 1916. After recovering from wounds sustained in the civil war, he recruited volunteers for the Estonian War of Independence and then joined the Aunus expedition as one of its commanders during Finland's "tribal wars" in 1919.
