An organisation that exists to further a profession and to protect both the public interest, by maintaining and enforcing standards of training and ethics in its profession, and the interest of its professional members.

An organisation that represents a group of people who are all part of the same profession, such as doctors or social workers. A professional body supports its members and may also make sure that the work they do is of a high enough standard. If you are unhappy with something that an individual professional has done, you may be able to complain to their professional body.
