Ludwig is a 1972 film by Italian director Luchino Visconti about the life and death of Ludwig II of Bavaria, mostly known today for his blind admiration for Richard Wagner and his commissioning of many palaces in Bavaria such as Neuschwanstein and Herrenchiemsee. Visconti's muse, Helmut Berger, stars as Ludwig, while Romy Schneider reprises her role as Elizabeth of Austria ("Sissi") from her 1950s Elizabeth trilogy.

Ludwig was a surreal 1970s British-made children's cartoon animation about a magical egg-shaped robot who lived in a forest. The character's name came from Ludwig van Beethoven, whose music played in the background of each episode. The series consisted of 65 five-minute episodes, in each of which something would happen to the animals of the forest and Ludwig would come to the rescue.

Ludwig is a small lunar impact crater that is located just beyond the eastern limb of the Moon, placing it on the far side from the Earth. It lies just to the east of the much larger Hirayama crater, and to the north of the Ganskiy crater.
