Maryland Route 108 (MD 108) is a state highway in the U.S. state of Maryland. The highway runs 34.23 miles (55.09 km) from MD 27 in Damascus east to MD 175 in Columbia. MD 108 is an S-shaped highway that winds through northern Montgomery County and central Howard County. The highway connects the Montgomery County communities of Laytonsville, Olney, Sandy Spring, and Ashton with the Howard County villages of Highland and Clarksville. MD 108 serves as the northern edge of Columbia and connects several of the planned community's suburban villages.

MD 108 originally connected Damascus with Olney. This highway was constructed between the mid-1920s and early 1930s. MD 108 from Olney to Columbia, part of Clarksville Pike, was originally constructed as MD 28 from Olney to Ashton and the original MD 27—later U.S. Route 29 (US 29)—from Ashton to Columbia. The highway was constructed near Columbia in the mid-1910s and from there to Olney in the late 1910s. MD 108 east of US 29 originally consisted of a county road and MD 531, which was built in the early 1930s and later became MD 175. MD 108 was extended east from Olney to Ashton in the mid-1940s and from Ashton to MD 175 in 1960 after US 29's present highway was built. The highway was extended to its present eastern terminus in the mid-1970s. MD 108 was expanded to a divided highway in Columbia in the late 1980s and in Olney in the mid-1990s.
