Rowlett (, traditionally ) is a city in Dallas and Rockwall counties in the U.S. state of Texas, and an eastern suburb of Dallas. The population was 67,339 as of the 2019 census est. It is a growing, upscale community with nearly $1.5 billion in development in the Dallas–Fort Worth metroplex, located on Lake 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 the Trinity River. The creek in turn was named for a waterway running through the property of Daniel Rowlett who moved from Kentucky 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.
The town was later renamed "Rowlett". The Dallas and Greenville Railway passed through the town in 1886, connecting Dallas with Greenville, Texas, and the Missouri–Kansas–Texas Railroad. Shortly after its opening, the line was formally sold to the MKT.
In 1921 the town was a stop on the Bankhead Highway.
