Maryland Route 212 (MD 212) is a state highway in the U.S. state of Maryland.
 The highway runs 10.43 mi from the District of Columbia boundary in Chillum north and east to U.S. Route 1 (US 1) near Beltsville.
 MD 212 connects the northern Prince George's County communities of Chillum, Langley Park, Adelphi, Hillandale, Calverton, and Beltsville.
 The highway was constructed from Washington to Adelphi in the early 1910s and extended north through Adelphi to Hillandale in the early 1930s.
 A separate portion of MD 212 was built from west of US 1 through Beltsville to what is now MD 201 in the early 1930s; the two sections were unified in the early 1940s.
 The route was expanded to a divided highway south of Langley Park in the early 1960s and at Interstate 95 (I-95) in the early 1970s.
 MD 212's eastern terminus was relocated north of Beltsville after a series of county highways were upgraded and brought into the state highway system in the 2000s and early 2010s; the old highway through Beltsville to MD 201 became MD 212A.

 Beck had grave misgivings regarding the Nazi demand that all German officers swear an oath of fealty to the person of Hitler in 1934, though he believed that Germany needed strong government and that Hitler could successfully provide this so long as he was influenced by traditional elements within the military rather than the SA and SS.
