The Office of Professional Responsibility (OPR) is part of the United States Department of Justice (DOJ) responsible for investigating attorneys employed by the DOJ who have been accused of misconduct or crimes in their professional functions. The OPR promulgates independent standards of ethical and criminal conduct for DOJ attorneys, while the DOJ's Office of the Inspector General (OIG) has jurisdiction of non-attorney DOJ employees. From 2009 to November 2012, the OPR was headed by Mary Patrice Brown.

The OPR receives reports of allegations of misconduct made against DOJ attorneys from many sources. Nearly half of all such allegations are reported to OPR by DOJ sources, such as the attorney involved. The remaining complaints come from a variety of sources, including private attorneys, defendants and civil litigants, other federal agencies, state or local government officials, judicial and congressional referrals, and media reports. OPR gives expedited attention to judicial findings of misconduct.

Professional responsibility is the area of legal practice that encompasses the duties of attorneys to act in a professional manner, obey the law, avoid conflicts of interest, and put the interests of clients ahead of their own interests.
