Marked Tree is a city in Poinsett County, Arkansas in the United States, along the St. Francis River, at the mouth of the Little River. The population was 2,800 at the 2000 census. It is included in the Jonesboro, Arkansas Metropolitan Statistical Area. The city got its name from a tree located on the bank of the St. Francis River until 1890 that had been slashed to mark a section of the river where Indians could walk about 120 yards (110 m) across land to reach the Little River and avoid paddling twelve miles (19 km) upstream. It is the only city in the World with that name.
