Carl Roth was a Swedish blacksmith, farrier, and ironmaster who lived during the mid-18th century.

He is best known for his work renovating Charles XII's Stair at Katarina Church in Stockholm, Sweden; and as ironmaster of both Duvnäs (Duvenäs), and Nedre Fösked (Föske) ironworks.

On 24 January 1729, at the age of 17, he enrolled as an apprentice farrier at the workshop where his father was the master.

They acquired a home in Packartorget, now called Norrmalmstorg, in Stockholm, where their sons Benjamin and Carl were born.

It was said that Carl was a man of great strength and endurance and he could, for example, ride all the way between Stockholm and Lower Fösked without stopping to rest (about 375 kilometers).
