The Anhalt Barn is a historic barn in rural eastern Logan County, Arkansas. It is located west of New Blaine, near the junction of Old Military and Artesian Well Roads.
It is a -story timber-frame structure with a gabled roof and a tall fieldstone foundation, laid out as a double crib with a central drive.
Built in 1878 by George Henry Anhalt, a German immigrant, it is the county's only known barn based on German barn-building principles.
It was listed on the National Register of Historic Places in 1993.
