A Southern Yankee is a 1948 American comedy western film directed by Edward Sedgwick and starring Red Skelton, Brian Donlevy and Arlene Dahl.

Skelton plays a Union soldier who spies on the Confederacy during the American Civil War.

Major Drumman's alluring accomplice Sallyann Weatharby enters and Aubrey falls in love with her.

Aubrey agrees to join Sallyann, posing as the Drumman, to a meeting with important Confederate spies.

Aubrey mixes up the plans and instructions and because he is wearing Confederate and Union uniforms at the same time, both armies shoot at him and he is knocked unconscious.

Kurt tells his men to dress in Union uniforms and intercept Aubrey (whom he believes to be Drumman) to steal the battle plans.
