Mississippi Highway 302 (also signed as Goodman Road) is the main east-west highway in DeSoto County, Mississippi, extending into Marshall County, Mississippi to the east. It runs approximately two miles south of the Mississippi/Tennessee state line, from a western terminus at Mississippi Highway 161 (old U.S. 61) in Walls, to U.S. 72 just west of Mount Pleasant.

For approximately one mile beginning at MS 161 and on eastward, MS 302 is a four-lane expressway to accommodate the U.S. 61 interchange. MS 302 then continues east from U.S. 61 to U.S. 78 at Olive Branch, mainly as a four lane highway with a center turn lane and significant commercial frontage. From U.S. 78 to MS 309, MS 302 is a four-lane expressway with at-grade intersections (with the exception of the overpass at Germantown Road/MS 305). Eastward from MS 309, the four-lane expressway continues, with a grade-separated interchange at the U.S. 72 terminus.
