A Christmas Pyramid (German: Weihnachtspyramide) is a Christmas decoration that has its roots in the Erzgebirge (Ore Mountains) of Germany but has become popular throughout the country. It is suggested that the Christmas pyramid is a predecessor of the Christmas tree; These pyramids themselves are not limited to Christmas: in the Erzgebirge existed a custom of dancing around the "St. John's Tree," "a pyramid decked with garlands and flowers," at the summer solstice.

It is a kind of Carousel with several levels some depicting Christian motifs, such as angels or manger scenes, and others with more secular motifs such as mountain-folk, forests, and other scenes from the everyday life of people in the Erzgebirge. The spinning motion of the pyramids is traditionally achieved with the help of candles whose rising heat spins a propeller above.
