The birthplace and childhood home of Martha Beall Mitchell, now the Martha Beall Mitchell Home and Museum, was added to the National Register of Historic Places in January 1978. On the second anniversary of her death, Martha Mitchell Expressway in Pine Bluff was named for her. Three years later to the day, a bust was erected in her honor at the Pine Bluff Civic Center with a plaque that reads "Ye shall know the truth and the truth shall make you free."
