The Davis–Bacon Act of 1931 is a United States federal law that establishes the requirement for paying the local prevailing wages on public works projects for laborers and mechanics. It applies to contractors and subcontractors performing on federally funded or assisted contracts in excess of $2,000 for the construction, alteration, or repair (including painting and decorating) of public buildings or public works.

The Davis–Bacon Act is part of the United States Code, codified as 40 U.S.C. 3141-3148.

The Act covers four main areas of construction: residential, heavy, buildings, and highway. Within these areas are further classifications, including craft positions such as plumber, carpenter, cement mason/concrete finisher, electrician, insulator, laborer, lather, painter, power equipment operator, roofer, sheet metal worker, truck driver, and welder.
