An injunction is a court order requiring the parties to whom it is addressed (the enjoined parties) not to engage in certain activity (a prohibitory injunction) or to engage in certain activity (an affirmative injunction), and is usually designed to maintain the current state of things (the status quo).

In Wyoming, an injunction is a legal remedy issued by a court that commands or prohibits specific actions by the parties involved. A prohibitory injunction prevents the enjoined parties from performing certain activities that could be harmful or violate the rights of the other party. Conversely, an affirmative injunction requires the parties to take specific actions. Injunctions are often sought to maintain the status quo, preventing any change that could cause irreparable harm before the court has a chance to fully consider the case. The process for obtaining an injunction in Wyoming typically involves the party seeking the injunction (the plaintiff) to file a complaint and a motion for a temporary restraining order and/or preliminary injunction. The court then assesses the immediacy and severity of the harm, the likelihood of success on the merits of the case, and the balance of equities between the parties. If the court grants a temporary restraining order or preliminary injunction, it may later be followed by a permanent injunction after a full hearing. Wyoming state statutes and rules of civil procedure, along with federal law if applicable, govern the issuance of injunctions.
