Newton County is a county located in the U.S. state of Mississippi. As of the 2020 census, the population was 21,291. Its county seat is Decatur.

The land that would become Newton County was purchased from the Choctaw under the terms of the Treaty of Dancing Rabbit Creek. Newton County was split off from the southern part of Neshoba County and organized on February 26, 1836. The county is named for scientist Isaac Newton.

The Battle of Newton's Station was fought in the county on April 24, 1863, during Grierson's Raid of the American Civil War. Union troops pulled up railroad tracks and burned the depot at Newton's Station.

In February 1864, General William Tecumseh Sherman crossed the county, burning the county seat at Decatur and was nearly captured during the Meridian Campaign. Sherman stopped during the return trip from Meridian and slept at Boler's Inn in the town of Union.

On October 8, 1908, a black sharecropper named Shep Jones had a disagreement with his white employer, leading to the employer's death. While searching for Jones, a white mob destroyed property owned by black people, burned their church and meeting lodge, threatened black families, and hanged Jones' father-in-law and two other black men. Many black people fled Newton County. No arrests or restitution occurred.

According to the U.S. Census Bureau, the county has a total area of 580 square miles (1,500 km), of which 578 square miles (1,500 km) is land and 1.5 square miles (3.9 km) (0.3%) is water.
