The Sphinx (Romanian: Sfinxul) is a natural rock formation in the Bucegi Natural Park which is in the Bucegi Mountains of Romania. It is located at an altitude of 2,216 metres (7,270 ft) within the Babele complex of rock formations.

The first photo of the Great Bucegi Sphinx was probably taken in about the year 1900. This photograph was taken from a front position, not from a lateral one, as it usually appears in modern pictures. It only acquired its nickname, referring to the Great Sphinx of Giza, in the year 1936. The image of the sphinx appears when the rock, having an 8 m height and a 12 m width, is observed from a certain angle. The megalith has its clearest outline on 21 November, at the time the sun goes down.
