Arinna was the major cult center of the Hittite sun-goddess known as dUTU URUArinna or "Sun-Goddess of Arinna", who is also sometimes identified as Arinniti or as Wuru(n)šemu. Arinna was located near Hattusa, the Hittite capital.
The Sun-Goddess of Arinna is the most important one of three important solar deities of the Hittite pantheon, besides dUTU nepisas 'the sun of the sky' and dUTU taknas 'the sun of the earth'.
In the late 14th century BC, King Mursili II was particularly devoted to the Sun-Goddess of Arinna.
