Bénédict Pierre Georges Hochreutiner was a Swiss botanist and plant taxonomist.
A native of Saint-Gall, he studied theology and natural sciences in Geneva. In 1896 he was an assistant to John Isaac Briquet at the Conservatoire et Jardin Botaniques at Geneva. In 1901 he made a scientific trip to Algeria, and in 1903–05 was associated with the botanic gardens at Buitenzorg in the Dutch East Indies. In 1906 he was named curator of the Conservatoire et Jardin Botaniques, where in 1931 he was appointed director. In 1919 he became a professor of botany.
As a taxonomist, he circumscribed many botanical species. The genus Hochreutinera is named after him, as are taxa with specific epithet of hochreutineri. Among his numerous written works was a monograph on the plant family Malvaceae.
