is a city in Weber County, Utah, United States, along Interstate 15. The population was 32,885 at the 2000 census. It is part of the Ogden–Clearfield, Utah Metropolitan Statistical Area.
Roy was settled in 1873, twenty-five years after Ogden; most of the surrounding communities had been settled prior to that time. On May 24, 1894 a post office was established in Roy. Previously known as Central City, Sandridge, the Basin, or Lakeview - Roy was not named until after the death of a local school teacher's child; Roy C. Peebles. The City of Roy was incorporated on March 10, 1937.
Businesses in Roy were limited until the early 1940s: a gas station, a couple of grocery stores, a cafe, and a lumber yard made up the modest business district. However, in 1943 Roy developed rapidly during World War II. Roy housed many of the workers and personnel from adjacent war bases: Hill Air Force Base, the Navy Supply Depot, and the Defense Supply Depot.
September 1953 marked a milestone in Roy's history—Roy received a charter to establish the first branch bank in the state of Utah. This branch of the Bank of Utah pioneered the way for other banks to establish branches through out the state.
Today, Roy boasts of most types of businesses and services. Roy was designated as "Weber County's Fastest Growing City," with a population of 24,603 in 1990 and 32,885 in 2000 census. A 2004 estimate places the population at 35,308. There are sewer, gas, and electrical systems and three water systems: the canal, a culinary water system, and a secondary water system. A large museum was built in 1993 and contains memorabilia of Roy City to preserve for others something of Roy's past.
