East Layton is a former city in Davis County, Utah, United States. Adjacent to Layton, it was incorporated in 1936 in order to secure funding for a community water system. East Layton remained a small, steadily growing residential town for decades, becoming a city in 1972. Rapid expansion during the 1970s led to a merger in 1981 with Layton, now Davis County's most populous city and one of the largest in Utah.
