Médéric de Vasselot de Régné (4 August 1837 – 23 April 1919) was a French-born forest officer trained at the National School of Forestry in Nancy, France.

Médéric and his older brother Marin Gabriel were sons of Jean Gabriel Charles Auguste de Vasselot de Régné (1780–1842) and Eugénie Gabrielle Elisabeth Selima Vasselot de la Chesnaye (1807–1879).

When he left Cape Colony in 1891, the forests of George, Knysna, and the Tsitsikamma National Park were being managed scientifically.

"Introduction of Systematic Treatment to the Crown Forests of the Cape Colony"[3] was first released, and a pamphlet entitled "Selection and Seasoning of Wood"[4] was released later in the year.

He was married on 5 October 1863, to Louise Suzanne Robinet de Plas (1844–1922), the daughter of Louis Augustin Ludovic Robinet de Plas (1813–1899) and Louise Marie Claire Picher (1824–1893).
