Hamlin is a city in Jones and Fisher Counties in the U.S. state of Texas. The population was 2,124 at the 2010 census, and in 2018, the estimated population was 1,997. The Jones County portion of Hamlin is part of the Abilene, Texas metropolitan area.
The city was named for W. H. Hamlin, a railroad official of the Kansas City, Mexico and Orient Railway. The Orient reached Hamlin in 1906 and was followed by the Texas Central Railroad within a few years and by the Abilene and Southern Railroad in 1910. The arrival of the railroad was announced in 1902, and the first train arrived in 1906. The county's first gypsum plant was constructed 6 miles (10 km) outside of Hamlin in 1903. Business boomed with the rail service, and the town included gins, a cottonseed oil mill, and a number of other businesses. Oil was discovered in 1928, which also contributed to the economy. The Hamlin Herald was first published in 1906 and is still in print.
