Booth and Flinn (1876–1950) was one of the largest American general contracting companies of its era.
It was established during the nineteenth century and was headquartered in Pittsburgh, Pennsylvania, United States.
The firm's origins were entwined with the Republican Party machine of the political bosses Flinn and Christopher Magee (1848–1901), his partner in politics, that controlled the city of Pittsburgh for the final twenty years of the 19th century.
As a result of politics and a "lowest responsible bidder" scheme, Booth and Flinn won most large construction and paving contracts in Pittsburgh and Western Pennsylvania, where they built streets, trolley lines, and bridges, usually amid charges by competitors of graft.
