Maryland Route 191 (MD 191) is a state highway in the U.S. state of Maryland.
 Known for most of its length as Bradley Boulevard, the highway runs 7.16 mi from MD 190 in Potomac east to MD 185 in Chevy Chase.
 MD 191 serves an affluent area with many golf courses as it connects Potomac and Chevy Chase by way of an S-shaped path through Bethesda in southwestern Montgomery County.
 Bradley Lane, the name for the Chevy Chase portion of the highway, was paved by 1910.
 This included the segment of the lane between MD 185 and MD 186, which was removed from the state highway in the 1940s.
 The remainder of MD 191 was constructed along mostly new alignment through Bethesda and Potomac in the early 1920s.
 The highway originally continued beyond its present western terminus and looped south along Persimmon Tree Road to Cabin John.
 MD 191 was expanded to a divided highway between what is now MD 355 and MD 614 in two portions in the 1940s and 1960s.
 The highway was relocated at its Persimmon Tree Road crossing of Interstate 495 (I-495) when the freeway was built in the early 1960s.
 The Cabin John–Potomac portion of MD 191 was removed from the state highway system in 1999.
