A nurse registry, nursing registry, or register of nurses is a list of nurses who are legally licensed to practice nursing. The register is maintained by the licensing body designated by law to regulate the profession. This is the source of the legal title "Registered Nurse". Usually each nurse is issued a unique identification or license number.

More information about registration and regulation can be found under country headings in the article Nurse.

In the United States, the term nurse registry is also commonly used to refer to a nursing agency, a private business which provides per diem or locum tenens nursing personnel to hospitals, medical offices and individuals.
