The Battle of Leuctra (or Leuktra) is a battle fought on July 6, 371 BCE, between the Boeotians led by Thebans and the Spartans along with their allies amidst the post-Corinthian War conflict.

The battle takes place in the neighborhood of Leuctra, a village in Boeotia in the territory of Thespiae.

The Theban victory shatters Sparta’s immense influence over the Greek peninsula that Sparta had gained since its victory in the Peloponnesian War.
