Roy is a city in Weber County, Utah, located on the west side of Interstate 15. The population estimate in 2019 was 39,613, a minimal increase of 5.8% from the official 2010 United States Census count of 36,884. It is part of the Ogden−Clearfield, Utah Metropolitan Statistical Area, and is considered a suburb of nearby Ogden, although some small businesses are present in Roy.
Roy was settled in 1873 by William Evans Baker, twenty-five years after Ogden. Most of the communities to the east and south had been settled prior to that time. Previously known as Central City, Sandridge, the Basin, and Lakeview—Roy was ultimately named for a local school teacher's child, Roy C. Peebles, who had died. On May 24, 1894, a post office was established and Roy's name was made official. The City of Roy was incorporated on March 10, 1937. Joseph William Jensen was the first mayor of Roy for 6 years, as elected by the commissioners.
Businesses in Roy were limited until the early 1940s. A gas station, several grocery stores, a cafe, and a lumber yard made up the modest business district.
