Melissa is a city in Collin County, Texas, United States. The population was 4,695 at the 2010 census, up from 1,350 at the 2000 census.
Some of Melissa's first settlers came from the old Highlands community, two and a half miles north of present-day Melissa. C.H. Wysong was one of the earliest settlers. A post office was established in 1853. The Houston and Texas Central Railroad was built in Melissa in 1872. The town was laid out at this time. The railroad encouraged many families to come to Melissa. The town is believed to have been named for the daughter of a railroad executive, George A. Quinlan (1838–1901) of the Houston and Texas Central Railroad. There is some disagreement about this, as others argue that the town was named after Melissa Huntington, daughter of C. P. Huntington, another well-known railroad executive.
