Beecher Island is a sandbar located along the lower course of the Arikaree River, a tributary of the North Fork of the Republican River near Wray in Yuma County, Colorado. The site is notable for having been the scene of an 1868 armed conflict between elements of the United States Army and several of the Plains Indian tribes. The island was named for Lt. Fredrick Henry Beecher of the 3rd Infantry (nephew of Henry Ward Beecher and veteran of the Battle of Gettysburg), one of the heroes of the engagement who was killed during what became known as the Battle of Beecher Island. The "island" and the courses of the river have been modified by several floods since 1868.
