瓦尔特堡(Wartburg)位在德国图林根的城堡，属艾森纳赫市，为罗曼式建筑。由路德因·德·史宾格(Ludwig der Springer)于1073年起建，1999年列为世界文化遗产。对于他的命名有一个笑话性传说，路德因·德·史宾格建堡时，当他第一眼看到这个地点，他说：“等一下，山麓--你将成为我的城堡！”（Wart', Berg--du sollst mir eine Burg werden!，德文的Wart为等待之意）。

1867年路德维希二世访问瓦尔特堡，后来修建新天鹅堡时参考了瓦尔特堡的宴会厅。

The Wartburg is a castle originally built in the Middle Ages. It is situated on a 410 meters (1,350 ft) precipice to the southwest of, and overlooking the town of Eisenach, in the state of Thuringia, Germany. In 1999, UNESCO added Wartburg Castle to the World Heritage List. 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 legendary Sängerkrieg. It was an important inspiration for Ludwig II when he decided to build Neuschwanstein Castle. Wartburg is the most-visited tourist attraction in Thuringia after Weimar. Although the castle today still contains substantial original structures from the 12th through 15th centuries, much of the interior dates back only to the 19th-century period of Romanticism.
