A kidney dish (British English) or emesis basin (American English) is a shallow basin with a kidney-shaped base and sloping walls used in medical and surgical wards to receive soiled dressings and other medical waste. Generally, the volume of a pulp kidney dish (or "vomit dish") is 700 mL. Its length is 25 cm-26 cm, its width 11 cm. The shape of the dish allows it to be held against the patient's body to catch any falling fluids or debris. Various sizes of emesis basins are common in healthcare settings, including facilities such as nursing homes that may have bedridden patients.

Reusable kidney dishes are usually made of stainless steel. During the first half of the 20th century, kidney dishes were commonly made of enamelled iron.

The disposable version of kidney dishes was invented by Bessie Virginia Blount, and they may be made of paper pulp or plastic. Disposable molded pulp kidney dishes have been replacing reusable kidney dishes because single-use products can decrease cross-communication of pathogens. Each year, more than 100 million pulp kidney dishes are used in hospital or family care.
