Merrick is a hamlet and census-designated place (CDP) in the Town of Hempstead in Nassau County, New York, United States. As of the 2010 census, the CDP population was 22,097.
When Europeans arrived, the place was called "Meroke" all along the South Shore of what is now Nassau County. After Sachem Tackapousha signed a treaty with Merrick's first colonists in 1643, Puritans who fled England started settling there. During the colonial period, Merrick became a trading center because vessels could enter Jones Inlet and sail up deep channels to docks beside what is now Merrick Road. During the War of 1812 these channels, canals and coves made Merrick a haven for buccaneers who preyed on merchants. Pirates in whaleboats once robbed prominent landowner George Hewlett and two friends while they were duck hunting, ripping the silver buttons from their coats. At one point, residents armed with muskets captured one bandit leader and shipped him to New York in irons for trial.
