Astor is an unincorporated community and census-designated place (CDP) in Lake County, Florida, United States.The population was 1,487 at the 2000 census.
The Astor area and much of the land along the St. Johns River was inhabited by Timucua natives prior to settlement by Europeans. Early attempts at settlement included an English trading post in 1763, and in 1822 a plantation growing sugar cane and oranges was established by Jewish immigrant Moses Elias Levy.In 1874, William Backhouse Astor, Jr. from New York City's wealthy Astor family purchased over 12,000 acres (49 km2) of land, upon which he began to establish a town he called Manhattan. New settlers arrived by steamboat to the town which Astor had endowed with a church, schoolhouse, botanical garden, and free cemetery. William Astor also built a hotel, saw mill, and eventually a railroad, the St. John's and Lake Eustis Railway, which departed town headed inland towards the communities of Eustis and Leesburg. A few miles to the west of town, a satellite community called Astor Park grew up along the shore of Lake Schimmerhorn (named for Astor's wife, Caroline Schermerhorn Astor). Over the next twenty years Astor saw his town grow, but the Manhattan name never caught on. When William Astor died in 1892, the town was officially renamed Astor in his honor.
