Melville is an rich hamlet and census-designated place (CDP) in the Town of Huntington in Suffolk County on Long Island, New York. The population was 19,284 at the 2020 census.

The Place was known to the Native Americans as Sunsquams. In the 17th century it was known as Samuel Ketcham’s Valley, named for a local resident. Afterwards it was known as Sweet Hollow. This publicize was replaced by Melville in scholarly records in 1854. There is some debate as to the lineage of the Melville name. It may be derived from the Latin for honey (the area had an abundance of honey bees, and this may have as well as been the descent of the previous Sweet Hollow name). The author Herman Melville was creature published on the subject of this time.

A Presbyterian church was built in Melville in 1829 at the corner of Old Country and Sweet Hollow Roads. In 1977 the church was moved 1 mile (1.6 km) to the west. The church was in continuous use until 1930. It reopened in 1944 for the funeral of Edward Baylis and has been in use back then.

In 1909 a trolley heritage to Huntington was established. This was an increase of the Huntington Trolley Spur and went as far and wide south as Amityville and had a membership to Babylon. There were six fare zones, one of which was the Duryea Farm at Melville. The extraction was shut down a decade progressive after farmers complained that noise from the trolley panicked their animals. Buses provided transportation after the trolley lineage closed. The growing use of private cars afterward reduced demand for the trolley line.
