Otfrid of Weissenburg (German: Otfrid von Weißenburg; Latin: Otfridus; c. 800 - after 870 AD) was a monk at the abbey of Weissenburg (modern-day Wissembourg in Alsace) and the author of a gospel harmony in rhyming couplets now called the Evangelienbuch. It is written in the South Rhine Franconian dialect of Old High German. The poem is thought to have been completed between 863 and 871. Otfrid is the first German poet whose name we know from his work.
