Adolfo Orsi (1888 – 20 December 1972) was an Italian industrialist, known for owning the Maserati automobile maker.
Born within a poor family in San Lazzaro, near Modena, Orsi lost his father in 1899 - an event that forced him to start working at a very young age. In the late 1920s he started his own business as scrap iron, steel mill and farm equipment manufacturer, eventually employing hundreds of people from Modena and the surrounding area. Orsi soon started pursuing interests outside of the company, including running the trolley company of Moden, and being involved with the local soccer team, Modena F.C. in its successful early years. With his brother, Marcello, he was also involved in a Fiat dealership, the Fiat A.M. Orsi (1935).
In 1937 Orsi bought the financially troubled Maserati company, employing his son, Omar Orsi, as managing director; three of the Maserati Brothers were retained on ten-year contracts on the engineering team (1937–47). In 1940 Orsi moved the Maserati headquarters from Bologna to Modena, near the premises of his steel plants and spark plug manufacturing company, Fonderie Riunite. In 1949, with Maserati temporarily closed for restructuring, a steel mill workers' strike action following Orsi's refusal to hire communist workers resulted in a series of hard encounters on 9 June 1950, leaving a few protesters dead. When the foundries were reopened in 1952, Orsi decided to sell the company, splitting it with his siblings. Adolfo kept the Maserati car manufacturing business, his brother Marcello kept the foundries, and their sister Ida Orsi took charge of the motorbike manufacturing (the Società Anonima Fabbrica Candele Accumulatori Maserati, 1953–60).
The 1950s proved to be a successful decade for Maserati. Orsi hired his brother in-law Alceste Giacomazzi as new general director, and succeeded in luring Ferrari employee Alberto Massimino to Maserati (1944–52), as well as hiring the Argentine driver ace Juan Manuel Fangio (1953). Fangio went on winning the Formula One World Championship for Maserati in 1954 and 1957.
