late 3rd millennium BCE, 𒋾𒌷𒂵𒀀𒀭, ti-ri₂-ga-a-an)[1] was the 19th and last Gutian ruler in Sumer mentioned on the "Sumerian King List" (SKL).

Tirigan ruled for 40 days before being defeated by Utu-hengal of Uruk, c. 2050 BC.

Tirigan is mentioned extensively in the victory stele of his nemesis and successor, Utu-hengal (also known as Utu-Khegal and Utu-Hegal): The enemy troops established themselves everywhere.

In the south, in Sumer, he blocked the water from the fields, in the uplands he closed off the roads.

He captured Ur-Ninazu and Nabi-Enlil, generals of Tirigan sent as envoys to Sumer, and put them in handcuffs.
