Henry Küss (or Henry Kuss, sometimes Henri Küss, 19 June 1852 – 22 November 1914) was a French mining engineer.
After brilliant studies at the École Polytechnique and École des Mines he was placed in charge of the mineralogical sub-district around Grenoble.
While holding this position, he made overseas trips to Uruguay, Mozambique, Argentina, Peru, Bolivia, Spain, Tunisia and Australia (twice) to assess the potential of mining concessions, earning a high reputation among financiers.
He was appointed an inspector-general of mines, and made important contributions to mining education and mine safety and hygiene regulations.
