The Battle of Idstedt, fought on 25 July 1850 near the village of Idstedt in what is today Schleswig-Holstein, was a Danish victory in the First Schleswig War. The Danish force of 37,000, commanded by Gerhard Christoph von Krogh and Friderich Adolph Schleppegrell, defeated a Schleswig-Holstein army of 26,800 under Karl Wilhelm von Willisen.
