The Association of Corporate Counsel (ACC), founded as the American Corporate Counsel Association (ACCA) in 1983, is a professional association serving the business interests of attorneys who practice in the legal departments of corporations, associations and other private-sector organizations around the world.

ACC states that it has more than 40,000 members employed by over 10,000 organizations in 85 countries.

ACC members collaborate through regional chapters and practice area committees.

In 2015, the Australian Corporate Lawyers Association joined ACC to form ACC Australia.

ACC serves as the "voice of the in-house bar"[5] on issues of importance to in-house counsel, such as multi jurisdictional practice, attorney-client/solicitor-client privilege and right to provide pro bono services.
