Arik (Arieh) Einstein (, born January 3, 1939) is an Israeli singer-songwriter.

Einstein was a vocalist for Batzal Yarok (Green Onion), Shleeshiyat Gesher Hayarkon (Yarkon Bridge Trio) and Hahalonot Hagvohim (The High Windows). His collaboration with Shalom Hanoch and the Churchills planted the seeds for the first Israeli rock albums. He dominated the nascent Israeli Bohemia scene along with his best friend, Uri Zohar. Einstein's influence has been so profound that virtually all Israeli pop music can be traced back to musical projects in which he participated. He managed to infuse the new styles of Rock and Pop with a deep Israeli flavor.
