Samuel Elisée Bridel-Brideri (November 28, 1761, Crassier, Vaud – January 7, 1828) was a Swiss-German bryologist.
He studied at the University of Lausanne, and at the age of 19 began work as a tutor to the princes of Saxe-Gotha-Altenburg. In 1804 he was appointed Geheimer Legationsrath to the Privy Council, and later served as a librarian in Gotha.
He was the author of an important work on mosses titled Muscologia recentiorum (1797-1803), of which several supplements were published in the ensuing years. Later he published the two-volume Myologia universa (1826-27), which was an improved edition of his earlier work. In the latter work he introduced a new system for classification of mosses; a system which is no longer used.
The genus Bridelia was named in his honor by German botanist Carl Ludwig Willdenow (1765-1812). A portion of his herbarium is now housed at the Berlin Botanical Museum, and a number of his scientific papers are kept at the Forschungsbibliothek Gotha Schloss Friedenstein. He was also the author of Délassements poétiques, a well-received book of poetry.
