Friederike Lienig (née Berg) (December 8, 1790, Forstei Dubena, Finland â 7 June, 1855, Dresden) was an entomologist from the Russian Empire who also resided in the Kingdom of Prussia. At first self-taught, she was later instructed by Philipp Christoph Zeller at the technical high school in Meseritz. She was a Member of the Stettin Entomological Society.
She published her first list of lepidoptera in 1840; her second list (with Zeller) was published in 1846.
She described several new moths including Ortholepis vacciniella, Udea inquinatalis, Argyresthia pulchella and Coleophora deauratella with Zeller.
She was married to Georg Friedrich Lienig, a Christian preacher; they lived in Koknese.
Four species of tiny moths are named after her. One is Cosmopterix lienigiella.
