The Molly Maguires was an Irish 19th-century secret society active in Ireland, Liverpool and parts of the Eastern United States, best known for their activism among Irish-American and Irish immigrant coal miners in Pennsylvania. After a series of often violent conflicts, twenty suspected members of the Molly Maguires were convicted of murder and other crimes and were executed by hanging in 1877 and 1878. This history remains part of local Pennsylvania lore and the actual facts are much debated among historians.

A secret society is an organization about which the activities, events, inner functioning, or membership are concealed. The society may or may not attempt to conceal its existence. The term usually excludes covert groups, such as intelligence agencies or guerrilla warfare insurgencies, that hide their activities and memberships but maintain a public presence.
