Rusa IV (died 585 BC) was king of Urartu from 590 BC to 585 BC.
Rusa IV was the son and a successor of Rusa III, and the successor of Sarduri IV.
His name is mentioned on a number of clay tablets found at Karmir Blur (near Yerevan, Armenia), including tablets bearing his own royal inscriptions.
He is possibly the Hrachya (Armenian: Հրաչյա) mentioned by the Armenian historian Moses of Khorene.
