Mississippi Highway 172 (MS 172) is a state highway located in Tishomingo County, Mississippi. The route runs 12.074 mi (19.431 km) from U.S. Route 72 (US 72) near Burnsville east to US 72 near Oldham, just west of the Alabama border. The route is a two-lane undivided road its entire length and runs mostly through wooded areas. It also passes through the town of Iuka, where it has an intersection with MS 25.

What is now MS 172 was originally designated as part of the Lee Highway auto trail in 1920 before becoming part of US 72 when the U.S. Highway System was created in 1926. The route was briefly US 78 before being redesignated US 72 by 1932. The route was fully paved by the end of the 1930s and served as a part of US 72 until 1986, when a new divided highway was built to the south. By 1998, the former routing of US 72 was designated MS 172.
