The Shirt Tails were a mid-19th-century street gang based in the Five Points slum in Manhattan, New York, United States, who wore their shirts on the outside of their pants as 19th-century Chinese laborers would dress as a form of insignia and as a sign of gang group affiliation. Members kept their weapons—as many as three or four at a time—concealed beneath their shirts; this discreet measure stands in contrast to competing gangs who flaunted their weapons in order to intimidate.^{[citation needed]}

Never numbering more than a few hundred members, the Shirt Tails, like many other gangs, disappeared shortly before the American Civil War (although they did participate in a coalition of gangs under the Dead Rabbits and fought against the Bowery Boys during the New York Draft Riots), with its remaining members dissipating or joining other Irish gangs.
