The tort of breach of confidence is, in United States law, a common-law tort that protects private information conveyed in confidence.^[1] A claim for breach of confidence typically requires the information to be of a confidential nature, which was communicated in confidence and was disclosed to the detriment of the claimant.

Establishing a breach of confidentiality depends on proving the existence and breach of a duty of confidentiality. Courts in the United States look at the nature of the relationship between the parties. Most commonly, breach of confidentiality applies to the patient-physician relationship,^[2] but it can also apply to relationships involving banks, hospitals, insurance companies, and many others.^[3]

There is no tort of breach of confidence in other common-law jurisdictions such as the United Kingdom or Australia; however, there is an equitable doctrine of breach of confidence.^{[citation needed]}
