It was named after Emanuel Solomon, who owned the land that the town developed on.

The railway line in to the Port Pirie smelters (and previously to the town stations) runs along the southern boundary of Solomontown.

[3] The Port Pirie Junction station was newly built in 1937 as the break-of-gauge junction between the South Australian Railways broad gauge from the south and the Commonwealth Railways standard gauge from the north on the site of the older Solomontown station on the Port Pirie-Cockburn railway line.

(officially known as Port Pirie Junction with both names on the signboard)[4] The station was replaced and closed in 1967, and later demolished.

During World War II, Solomontown, now a suburb of Port Pirie, was the location of RAAF No.11 Inland Aircraft Fuel Depot (IAFD), built in 1942 and closed on 14 June 1944.
