On June 1, 1803, Revolutionary War veteran William Mason paid $1,700 at auction to purchase 640 acres of land in what is now downtown Mason. In 1815, he platted 16 lots on this land and named the village "Palmira." In 1832, 2 years after the death of William Mason and according to his will, over 40 more lots were platted on the north, south, and west of Palmira. When the plat was officially recorded, the name of the village was listed as "Palmyra."


In 1835, a petition was sent to the federal post office to correct the name of the town. It had been listed as Kirkwood, possibly an error because the postmaster at the time was William Kirkwood. When village officials were informed that there was another Palmyra in Ohio, the name was officially changed to "Mason." Mason remained a small farming community for another 125 years. In 1970, a year before the town was incorporated to become a city, there were fewer than 5,700 residents. Today, the City of Mason covers over 11,200 acres and is home to nearly 25,000 people and approximately 500 businesses.

The City of Mason continues to draw upon its history as it eagerly anticipates the future. It is increasingly being recognized as a rapidly growing, progressive community with an attractive industrial base. Known as a business-friendly community, it stands ready to work with developers and business owners to create a carefully planned and attractive community that serves both residents and businesses. The number of new businesses regularly looking to locate in Mason and the expansion of existing enterprises confirms Mason’s success. Cintas Corporation, Mitsubishi, Procter & Gamble's Health Care Research Center, and Luxottica Retail are among the premier companies located in Mason.

Mason is also recognized as the resort area of southwest Ohio. Paramount's Kings Island Amusement Park, The Beach Waterpark, and The Golf Center at Kings Island are among the prominent recreation destinations in Mason. Mason is home to the world-recognized Tennis Masters Series-Cincinnati as well as several well-loved local annual events. The Alverta Green Museum, operated by the Mason Historical Society, keeps the city in touch with its historical roots.
