Friedrich Wagenfeld (January 3, 1810 – August 26, 1846) was a German philologist and author born in Bremen.
From 1829 to 1832 he studied philology in Göttingen, and subsequently spent several years serving as a tutor in Brinkum. Afterwards he lived and worked as a writer in Bremen, where he died on August 26, 1846 at the age of 36.
Wagenfeld was the author a popular collection of Bremen folk tales titled Bremer Volkssagen (1844-45). In 1837 he published what purportedly was the entire text of Philo of Byblos' Sanchoniathon, which was reported to have been found in the Portuguese convent of Santa Maria de Merinhão. However this publication was soon afterwards proven to be a fabrication by several scholars.
