A Joint Venture (JV) is a cooperative enterprise entered into by two or more business entities for the purpose of a specific project or other business activity. The reason for a joint venture is usually some specific project.

Joint ventures can be informal (a handshake) or formal, and they can be short term or long term. Often the joint venture creates a separate business entity, to which the owners contribute assets, have equity, and agree on how this entity may be managed. The new entity may be a corporation, limited liability company, or partnership.
