François Sulpice Beudant (5 September 1787 – 10 December 1850), was a French mineralogist and geologist. The mineral beudantite was named after him.

In the following year the royal mineralogical cabinet was committed to his charge to be conveyed into England, and from that time his attention was directed principally towards geology and cognate sciences. In 1817 he published a paper on the phenomena of

In 1820, he was appointed to the professorship of mineralogy in the Paris faculty of sciences, and afterwards became inspector-general of the university. He subsequently published treatises on physics and on mineralogy and geology. Perhaps his most notable publication is the second edition of ''Traite Elementaire de Mineralogie'' (Paris, 1830–1832), the second volume of which deals with descriptive mineralogy and in which Beudant coined the names of many minerals, such as anglesite,
