Maryland Route 198 (MD 198) is a state highway in the U.S. state of Maryland. The highway runs 14.14 miles (22.76 km) from MD 650 near Spencerville east to the entrance of Fort George G. Meade beyond its junction with MD 32. MD 198 connects Laurel in far northern Prince George's County with the northeastern Montgomery County communities of Spencerville and Burtonsville and Maryland City and Fort Meade in western Anne Arundel County. The highway is a four-to-six-lane divided highway between U.S. Route 29 (US 29) in Burtonsville and the Baltimore–Washington Parkway in Maryland City.

MD 198 was constructed from US 1 in Laurel west toward Burtonsville in the early 1920s and completed in the late 1920s. Another section was built in Spencerville in the late 1920s; the two segments were connected in the mid-1950s. The Laurel–Fort Meade road was built as MD 602 for military access purposes in the mid-1940s, replacing the original highway between the two locations, MD 216. MD 198 was relocated through Laurel and extended east along MD 602 to Fort Meade in the early 1960s. The first divided highway portion of the highway was part of a relocation at the Interstate 95 (I-95) interchange in the early 1970s. The divided highway was extended west to Burtonsville in the mid-1980s and through Maryland City in the late 1980s. MD 198's eastern end was extended to MD 32 in the early 1990s and then moved again for its interchange with that highway in the early 2000s. The Maryland State Highway Administration (MDSHA) plans to expand the remaining two-lane portions of MD 198 to a divided highway.
