The Boston Vigilance Committee (1841–1861) was an abolitionist organization formed in Boston, Massachusetts, to protect escaped slaves from being kidnapped and returned to slavery in the South. The Committee aided hundreds of escapees, most of whom arrived as stowaways on coastal trading vessels and stayed a short time before moving on to Canada or England. Notably, members of the Committee provided legal and other aid to George Latimer, Ellen and William Craft, Shadrach Minkins, Thomas Sims, and Anthony Burns.

Members coordinated with donors and Underground Railroad conductors to provide escapees with funds, shelter, medical attention, legal counsel, transportation, and sometimes weapons. They kept an eye out for slave catchers, and spread the word when any came to town. Some members took part in violent rescue efforts.
