Kewell, who will turn 30 in September, spent five poor seasons at Liverpool plagued by injuries and was released last May.
A statement on Galatasaray's website said that the Australian winger is set to arrive in the next few hours to finalize the deal and join the pre-season camp.
Portsmouth and AS Roma were reportedly interested in signing him but Galatasaray had the best offer.
Kewell is hoping to boost his club career and so he scarified the Beijing Olympics despite being named among the over-age player in Australia squad.
