William Ewen (April 15, 1720 – January 24, 1777) was the first president of the Council of Safety of Georgia during the American Revolution. He is considered the state's first chief executive, although the first chief executive under a proper constitutional government (the "Rules and Regulations" of 1776) was Archibald Bulloch, and the first person to hold the title of (non-royal) "governor" was John A. Treutlen.
