From Ištar's Descent to the Netherworld:
"If you do not open the gate, that I may enter, I will break down the door, I will smash the bolt, I will break down the frame, I will topple the doors. I will break the ..., I will te[ar off the kn]ob. I will raise up the dead so that they devour the living, and the dead will outnumber the living."
We also have draugrs from Scandinavian mythology, although they don't quite fit into the modern view of zombies. They are, however malevolent reanimated bodies.
