Duke Ping of Qi (Chinese: 齊平公; pinyin: Qí Píng Gōng), personal name Lü Ao, was from 480 BC to 456 BC the duke of the Qi state.
[1][2] Duke Ping was a younger son of Duke Dao of Qi, who was killed in 485 BC after four years of reign, probably by Tian Heng, leader of the powerful Tian clan.
In 481 BC, Tian Heng staged a preemptive coup d'etat and killed Duke Jian and his prime minister Kan Zhi, who had been plotting to attack and expel the Tian clan.
Duke Ping ruled for 25 years and died in 456 BC.
He was succeeded by his son Duke Xuan of Qi.
