The Ostmärkische Sturmscharen (German pronunciation: [ˈɔstmɛʁkɪʃə ˈʃtʊʁmˌʃaːʁən]; 'Eastern March Stormtroopers') was a right-wing paramilitary group in Austria, founded on 7 December 1930.

Recruited from the Katholische Jugend (Catholic Youth), later from journeymen and teacher organisations, it formed an opposition to both to the nationalist Heimwehr forces and the Social Democratic Republikanischer Schutzbund.

[1] Founded in Innsbruck, Tyrol, the Ostmärkische Sturmscharen spread over the entire Austrian territory when the association's headquarters were relocated to Vienna in 1933.

On the eve of the Austrian Civil War, the Märkische Sturmscharen increasingly adopted a Catholic clerical fascist and antisemite stance.

On 11 April 1936, the Ostmärkische Sturmscharen declared themselves a cultural organisation, hence the final merger of all defence forces into the VF by decree of Chancellor Schuschnigg in October was for them merely a formality.
