[7] Soddy-Daisy was home to Hamilton County's first courthouse and government seat, Poe's Tavern.

During the Civil War, Poe's Tavern served as a hospital for both Union and Confederate troops.

The first is that the word "Soddy" is an anglicization of Tsati, a shorter form of the Cherokee word ᎠᏂ ᎫᏌᏘ Ᏹ (Ani-Kusati-yi), referring to the Muskogean Koasati people who lived there in the 18th century prior to Cherokee migration to the area after 1776.

The second theory is that Soddy was named for William Sodder, who ran a trading post in the city.

An inlet of Chickamauga Lake (consisting of the lower part of Soddy Creek) lies to the east.

State Route 111, which crosses Walden Ridge and leads 17 miles (27 km) northwest to Dunlap, intersects US-27 in the northern part of the city.

[15] As of the 2020 United States census, there were 13,070 people, 5,628 households, and 3,378 families residing in the city.

[19] Soddy-Daisy has one museum, which was opened in 2017 and remains operated by the city's historical association.

The museum, currently housed in the 100 year old former bank building in Soddy has exhibits that showcase and teach the history of Soddy-Daisy area.

The historical association also hosts an annual history fair at Soddy-Daisy High School every January.
