Glace Bay (Scottish Gaelic: Glasbaidh) is a community in the eastern part of the Cape Breton Regional Municipality in Nova Scotia, Canada.

When Cape Breton Island was returned to French control, Fort William continued in service until 1752 when it was destroyed by fire.

[5] At its high point the company operated eleven mines in all, and was responsible for 40% of Canada's coal production.

The S & L Railway's main operations, including the roundhouse and machine shops were located in Glace Bay.

Glace Bay's extensive coal and rail operations made the town the industrial center of Cape Breton.

[6] The Marconi National Historic Site of Canada is located at Table Head in Glace Bay.

[7] Parks Canada maintains an interpretive centre at the site honouring the role of Guglielmo Marconi in the development of radio communications.

In December 1902, Marconi transmitted the first complete messages to Poldhu from stations at Glace Bay, Nova Scotia.

In 1907 he initiated the first permanent transatlantic wireless service from Marconi Towers to its companion site in Clifden, Ireland.

Glace Bay experiences a cool summer, and windy, wet and stormy winter, a version of a humid continental climate (Köppen Dfb) that is significantly moderated by the community's proximity to the Atlantic Ocean.

Federally, Glace Bay is located in the riding of Cape Breton–Canso, currently held by Liberal MP Mike Kelloway.
