Mandarin is a neighborhood located in the southernmost portion of Jacksonville, in Duval County, Florida, United States. It is located on the eastern banks of the St. Johns River, across from Orange Park. Mandarin was named after the Mandarin orange in 1830 by Calvin Reed, a prominent resident of the area .

Once called "a tropical paradise" by author Harriett Beecher Stowe, the quaint area of Mandarin is marked by its history, ancient oak trees draped with Spanish moss, beautiful parks, marinas and more water views than any other area in Jacksonville. In the 19th century, Mandarin was a small farming village that shipped oranges, grapefruit, lemons and other fruits and vegetables to Jacksonville and points north on the steamships that traveled the St. Johns River. In 1864, the Union steamship, the Maple Leaf, hit a Confederate mine and sank just off Mandarin Point.
