The Battle of Iller River or Battle of Erolzheim (5 June 1800) saw a French Republican army led by Jean Victor Marie Moreau fight a Habsburg Austrian army led by Paul Kray. In late May, the adversaries reached a stalemate with the Austrian army holding Ulm and the French army facing it from the south. Both armies numbered about 80,000 men. Kray launched an attack against the French left wing along the Iller River at Erolzheim and Illertissen, but he withdrew his troops when Moreau sent reinforcements. The action occurred during the War of the Second Coalition, part of the French Revolutionary Wars.

The Iller River flows north past Memmingen, Erolzheim, and Illertissen in southern Germany and enters the Danube at Ulm.
