The first Wartburg Festival was a convention of about 500 Protestant German students, held on 18 October 1817 at the Wartburg castle near Eisenach in Thuringia. The former refuge of reformer Martin Luther was considered a national symbol and the assembly a protest against reactionary politics and Kleinstaaterei.

The Wartburg is a castle originally built in the Middle Ages. It is situated on a precipice of 410 metres (1,350 ft) to the southwest of and overlooking the town of Eisenach, in the state of Thuringia, Germany. It was the home of St. Elisabeth of Hungary, the place where Martin Luther translated the New Testament of the Bible into German, the site of the Wartburg festival of 1817 and the supposed setting for the possibly legendary Sängerkrieg. It was an important inspiration for Ludwig II when he decided to build Neuschwanstein Castle.
