Christmas ornaments, baubles, globes, "Christmas bulbs", or "Christmas bubbles" are decoration items, usually to decorate Christmas trees. These decorations may be woven, blown, molded, carved from wood or expanded polystyrene, or made by other techniques.

A Christmas tree is a decorated tree, usually an evergreen conifer, such as a spruce, pine or fir, or an artificial tree of similar appearance, associated with the celebration of Christmas.
