Gallus Mag (real name unknown) was a six-foot-plus tall, female bouncer at a 19th-century New York City bar called The Hole in the Wall. She figures prominently in New York City folklore. The name "Gallus" originated from the men's suspenders she was fond of wearing and "Mag" or "Meg" was likely her forename. The Hole in the Wall bar was at 279 Water Street, Manhattan, more recently the site of the historic Bridge Cafe.

Herbert Asbury's book The Gangs of New York referenced her as one of Charley Monnell's "trusted lieutenants," along with Kate Flannery. He described her: According to legend, Gallus Mag's ghost still haunts the building.
