Gao Yanzong (高延宗) (died c.November 577), often known by his princely title of Prince of Ande (安德王), was an imperial prince of the Chinese Northern Qi dynasty, who briefly claimed the imperial title in 577 for three days as his cousin, the emperor Gao Wei, fled in the face of an attack by rival Northern Zhou. Traditional historians usually did not consider him an emperor of Northern Qi.
