Rowlett is a city in Dallas and Rockwall counties in the U.S. state of Texas, and a northeastern suburb of Dallas. The population was 56,199 as of the 2010 census. It is a quiet, upscale bedroom community in the Dallas–Fort Worth metroplex, located onLake Ray Hubbard.
Rowlett derives its name from Rowlett Creek, which flows into Lake Ray Hubbard and is a major tributary of the east fork of theTrinity River. The creek in turn was named for a waterway running through the property of Daniel Rowlett who moved fromKentucky to Bonham, Texas, in 1835. Daniel, who was a member of the Smoot-Rowlett political family, had no direct dealings with the town that now bears his name. The first post office opened on April 5, 1880, and it was called "Morris" after Postmaster Austin Morris.
