This is a list of Maryland State Historical Markers which were first placed in Maryland in 1930. The Maryland Department of Transportation (MDOT), in partnership with the Maryland Historical Trust (MHT), reviews marker applications while the MDOT Maryland State Highway Administration (SHA) funds, installs, and maintains the markers along state roads and property. The current program was launched in 1933 due to an explosion of automobile ownership within the state. There were 766 markers as of October 2020.
