Ironton is an extinct town located in Ouray County, Colorado, United States.

Ironton (also formerly named "Copper Glen") was built on flatter ground than surrounding towns.

Settled sporadically through the 1870s and 1880s, a major period of settlement that solidified Ironton as a community saw roughly 300 structures begin construction during a three-week span.

[5] Ironton was a major transportation junction between Red Mountain Town and Ouray in addition to having some of its own mines.

This narrow gauge railroad backed by noted financier Otto Mears reached Ironton in 1889.
