The population was 20,438 at the time of the 2020 census. The area currently known as Lynbrook has had other names, including Rechquaakie, Parson's Corners, and Bloomfield. It was later named Pearsall's Corners, after Mr. Pearsall's General Store, because this store became a famous stagecoach stop for travelers coming from New York City to Long Island. Alternatively, it was called "Five Corners" because the stagecoach stop was at the crossing of Hempstead Avenue, Merrick Road, and Broadway. It became known as Lynbrook in 1894 and the village was incorporated in 1911. The name "Lynbrook" is derived by dividing "Brooklyn" into its syllables and transposing them, a tribute to the original home of many of the town's turn-of-the-century residents.
