The Battle of Tegyra (375 BC) (also known as the Battle of Tegyrae) was an ancient Greek battle between Theban and Spartan hoplite forces. In the battle, a Theban army under Pelopidas was challenged by a substantially larger Spartan force while retreating from an abortive attack on Orchomenus, but successfully attacked and routed the Spartans. The battle marked the first occasion in the historical record in which a Spartan force had been defeated by a numerically inferior enemy in a set battle (as opposed to irregular warfare, employed by Iphicrates).
