Ding are prehistoric and ancient Chinese cauldrons standing upon legs with a lid and two fancy facing handles. They are one of the most important shapes used in Chinese ritual bronzes. They were made in two shapes: round vessels with three legs and rectangular ones with four, the latter often called fāng dǐng "square ding (方鼎. They were used for cooking, storage, and ritual offerings to the gods or to ancestors.

Sets and individual examples of ritual bronzes survive from when they were made mainly during the Chinese Bronze Age. Ritual bronzes create quite an impression both due to their sophistication of design and manufacturing process, but also because of their remarkable durability. From around 1650 BCE, these elaborately decorated vessels were deposited as grave goods in the tombs of royalty and the nobility, and were evidently produced in very large numbers, with documented excavations finding over 200 pieces in a single royal tomb. They were produced for an individual or social group to use in making ritual offerings of food and drink to his or their ancestors and other deities or spirits. Such ceremonies generally took place in family temples or ceremonial halls over tombs. These ceremonies can be seen as ritual banquets in which both living and dead members of a family were supposed to participate. Details of these ritual ceremonies are preserved through early literary records. On the death of the owner of a ritual bronze, it would often be placed in his tomb, so that he could continue to pay his respects in the afterlife; other examples were cast specifically as grave goods. Indeed, many surviving examples have been excavated from graves.
