Soso is a town in Jones County, Mississippi, United States. The population was 418 at the 2020 census.

Paul Davis, a singer and songwriter from Meridian, Mississippi, wrote a song called "Sweet Magnolia Blues", which refers to Soso.

According to tradition, the name "Soso" was derived from an old settler's common response to a question about how he was doing: "so-so".

After the Civil War, yeoman farmers returned to the area. The town developed a small mixed-race community. Among its notable residents was Unionist Newton Knight, who lived there mostly after the Reconstruction era with his wife Rachel and family. Knight was known for having led the Knight Company in and around Jones County during 1863 and 1864 in resistance to Confederate authorities, trying to protect local farmers. After the war he lived in Jasper County for a time, where he was active in the Republican Party. In 1872 he was appointed as a deputy U.S. Marshal for the Southern District. After Reconstruction ended, Knight retired from politics, as white Democrats took over county and state offices.

Rachel was a freedwoman who had aided the resistance. (In an historic photograph she appears to have been of mixed race.) She and Knight had several children together.

On April 12, 2020, Soso was struck by a 2.25-mile-wide EF4 tornado. It caused major damage to homes, churches, and the fire station. Numerous trees were snapped throughout town, the old elementary school was damaged, multiple buildings and churches in town were leveled and several homes were destroyed. The tornado's path mirrored that of a long-tracked F3 tornado that struck the south side of town on April 21, 1951, also causing severe damage.
