Kokinis, who was the Ravens' director of pro personnel from 2003 to 2008 before leaving for Cleveland, was named Baltimore's senior personnel assistant on Tuesday.
"It's good to have George back," general manager Ozzie Newsome said in a statement released by the team. "He will help evaluate college and pro players, plus work with Pat [Moriarty], the Ravens' vice president of football [administration].
"George knows the game, understands what it takes to win, and he will help us find players who will help us win. He has done that before for us."
In February, Kokinis resolved a grievance he filed against the Browns after he was fired in November.
The terms of the settlement were confidential. Kokinis was seeking more than $4 million on the balance of his five-year, $5 million contract with the Browns.
He claimed the Browns fraudulently induced him to join the team under the representation that he would have control over all player personnel matters and report directly to owner Randy Lerner.
