Mason is a city in southwestern Warren County, Ohio, United States, approximately 22 miles (35 km) north of downtown Cincinnati. As of the 2020 census, Mason's population was 34,792.^[5] It is home to Kings Island amusement park and one of the largest tennis stadiums in the world, the Lindner Family Tennis Center, home of the Cincinnati Open, one of the world's top tennis tournaments for both men and women.

On June 1, 1803, Revolutionary War veteran William Mason paid $1,700 at auction to purchase 640 acres (2.6 km²) of land in what is now downtown Mason. In 1815, he platted 16 lots on this land and named the village "Palmyra."

In 1835, a petition was sent to the federal post office to correct the name of the town. The town had been listed as Kirkwood, possibly an error because the postmaster at the time was named William Kirkwood. When village officials were informed that there was another Palmyra in Ohio, the name was officially changed to "Mason."

In 1923 Main Street was paved, prompting a celebration throughout the town.

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.^[6]

In February 1997, Mason withdrew from surrounding Deerfield Township by forming a paper township called Mason Township.^[7]

In 1928 the 50,000 watt, 831-foot WLW-AM tower was built on Tylersville Road. Six years after its construction President Franklin Roosevelt ordered the tower to operate 10 times it original power capacity. The new 500,000 wattage would be powerful enough to broadcast across the Atlantic ocean. This new strength would prove tedious for locals as they could hear the broadcast through their bedsprings, downspouts, and fencing.

After complaints from other radio stations due to signal interference, the power would eventually be reduced in 1939 after the Federal Communications Commission chose not to renew the experimental broadcast, reducing the wattage back to its original 50,000 capacity. This decision was appealed by the Crosley Corporation, the company who operated the tower, all the way to the supreme court where it was still denied.

According to the United States Census Bureau, the city has a total area of 18.67 square miles (48.36 km²), of which 18.63 square miles (48.25 km²) is land and 0.04 square miles (0.10 km²) is water.^[8] Additionally the city has a short border along the Little Miami River.
