The 1561 celestial phenomenon over Nuremberg was a mass sighting of celestial phenomena or unidentified flying objects (UFO) above Nuremberg, Germany. The phenomenon has been interpreted by some modern UFO enthusiasts as an aerial battle, possibly of extraterrestrial origin. This view is mostly dismissed by skeptics, some referencing Carl Jung´s mid-twentieth century writings about the subject.

Around dawn on April 14, 1561, residents of Nuremberg saw what they described as an aerial battle, followed by the appearance of a large black triangular object and then a large crash outside of the city. According to witnesses, there were hundreds of spheres, cylinders and other odd-shaped objects that moved erratically overhead.

A broadsheet news article was printed on April 14, 1561 describing the event. The broadsheet, illustrated with a woodcut engraving and text by Hans Glaser, measures 26.2 centimetres (10.3 in) by 38.0 centimetres (15.0 in). The document is archived in the prints and drawings collection at the Zentralbibliothek Zürich in Zurich, Switzerland.

The broadsheet describes objects of various shapes including crosses, globes, two lunar crescents, a black spear and tubular objects from which several smaller, round objects emerged and darted around the sky at dawn.
