Dáin I (Third Age 2440 – 2589, aged 149 years) was King of Durin's folk for 4 years, from 2585 to 2589. Dáin ruled during the period when his people lived in the Grey Mountains. His father was Náin II, and he had a younger brother Borin. Dáin had three children, Thrór, Frór, and Grór.
Dáin and his people were troubled by increasing dragon attacks, and eventually both Dáin and Frór were killed by a Cold-drake at the gate of his halls. After Dáin's death, Thrór and Grór led the Dwarves of Durin's folk south. Thrór led one group back to Lonely Mountain, while Grór founded his own kingdom in the Iron Hills.
