春秋五覇
Duke Huan of Tian Qi (; 400–357 BC) was from 374 to 357 BC ruler of the State of Qi, a major power during the Warring States period of ancient China. Duke Huan's personal name was Tian Wu (田午), and ancestral name Gui (媯). His official posthumous title was simply Duke Huan of Qi, but he is commonly called Duke Huan of Tian Qi to be distinguished from the original Duke Huan of Qi from the House of Jiang, who was the first of the Five Hegemons of the Spring and Autumn period.
