The International Brotherhood of Boilermakers, Iron Ship Builders, Blacksmiths, Forgers and Helpers (IBB), sometimes referred to as the International Brotherhood of Boilermakers, is a trade union in the United States and Canada. It is for boilermakers and related occupations, and is affiliated with the AFL–CIO.

The Boilermakers union has a four-year apprenticeship training program before becoming a journeyman. Boilermakers primarily work in nuclear and fossil power plants. However they also work in shipyards, refineries, chemical plants, manufacturing, and the rail and cement industries. The work involves welding, rigging and fabricating.
