"Mary Don't You Weep" (alternately titled "O Mary Don't You Weep", "Oh Mary, Don't You Weep, Don't You Mourn", or variations thereof) is a #Spiritual that originates from before the #AmericanCivilWar. As such, scholars sometimes refer to it as a "slave song", "a label that describes their origins among the enslaved", and it contains "coded messages of hope and resistance". It is considered "one of the most important Negro spirituals".
