FINRA is a private, self-regulatory organization that oversees broker-dealers and their registered representatives in the United States.

Created in 2007 through the merger of NASD and NYSE regulatory functions, FINRA writes and enforces rules governing broker-dealer firms, examines firms for compliance, and operates the largest securities dispute resolution forum. It is overseen by the SEC but is not a government agency. In Canada, a comparable self-regulatory body is CIRO.
