East Coweta High School (ECHS) is a public high school located in Coweta County, Georgia, United States. It serves about 3,300 students in grades 9 to 12 in the Coweta County School System.^{[citation needed]} Founded in 1946,^{[citation needed]} it is the second oldest high school in the county.^{[citation needed]}

East Coweta High School was founded on April 17, 1946 when the Coweta County School Board ordered that the Haralson, Raymond, Starr, and Senoia school operate East Coweta High School at Starr School for the ensuing year. This resulted from a series of consolidations begun years earlier. In the fall of 1988, the high school students of Moreland, East Newnan, White Oak, Major, the traditional East Coweta area, and all parts in between merged to culminate the consolidation efforts begun so long ago.^{[citation needed]}

These major consolidated schools ultimately resulted in the present East Coweta High School.
