Zhang Yanlang (Chinese: 張延朗) (died January 14, 937?) was an official of the Chinese Five Dynasties and Ten Kingdoms Period states Later Liang and Later Tang. He had his most powerful positions during the reign of Later Tang's last emperor Li Congke, as both chancellor and the director of the three financial agencies (taxation, treasury, and salt and iron monopolies). After Li Congke was overthrown by his brother-in-law Shi Jingtang, who established his own Later Jin, Shi ordered Zhang be put to death.
