Interstate 44 (I-44) in the U.S. state of Missouri runs northeast from the Oklahoma state line near Joplin to I-70 in downtown St. Louis. It runs for about 293 miles (472 km) in the state.

Interstate 44 enters Missouri in Newton County at the eastern terminus of the Will Rogers Turnpike, 200 yards south of the Kansas state line. The first interchange in Missouri is the eastern terminus of both U.S. Highway 166 and U.S. Highway 400. This highway next goes through southern Joplin and then begins a concurrency with Interstate 49/U.S. Highway 71 at Exit 11 just after entering Jasper County. The freeway turns to a more easterly heading (the old route of US 166), and then I-49/U.S. 71 splits off to the north at Exit 18.

I-44 next enters Lawrence County. Near Mount Vernon, the highway curves to the northeast. The section of highway to Halltown is a completely new highway, not supplanting any previous highways. At Halltown, the road curves back to due east, beginning to follow the general pathway of old U.S. Highway 66, which it does all the way to downtown St. Louis. I-44 then goes around the western and northern sides of Springfield, serving as the western terminus of the James River Freeway, as well as crossing both Route 13 and U.S. Highway 65. The Interstate Highway continues northeast, bypassing Lebanon.
