Wyoming is best classified as statutory stand-your-ground. Wyoming Statutes § 6-2-602 provides that a person attacked in any place where lawfully present does not have a duty to retreat before using reasonable defensive force, provided they are not the initial aggressor and not engaged in illegal activity. Wyoming is a statutory SYG state. That is what separates Wyoming stand-your-ground and the duty to retreat from a generic national summary. Read Wyo. Stat. Ann. § 6-2-602 before the background sections below. Criminal justification does not automatically end every civil claim.

Practitioners open Widdison v. State when Wyoming stand your ground turns on the distinction in this sentence: "RB, the biological father of SSO, entered an appearance to contest adoption proceedings and SSO’s foster parents, the petitioners for adoption, moved to strike his entry of appearance and objection to the adoption." Do not lift it out of the facts the court was deciding.
How stand your ground interacts with the castle doctrine
Even in duty-to-retreat jurisdictions, the home is special. Wyoming occupants should read this page together with Castle Doctrine in Wyoming, which covers intruder scenarios, presumptions of fear, and vehicle/workplace extensions.
Practical takeaways for Wyoming
- Know whether you are in a covered place (home, vehicle, workplace, or any place you have a right to be).
- Document lawful presence and the facts supporting a reasonable belief of imminent death or great bodily harm.
- Expect prosecutors to probe initial-aggressor status, mutual combat, and any alleged criminal activity.
- If Wyoming offers immunity, ask counsel about pretrial procedures early.
Frequently asked questions
Does Wyoming have stand your ground laws?
Yes. Wyoming recognizes a statutory stand-your-ground rule: a person who is lawfully present and otherwise justified generally need not retreat before using deadly force.
Is there a duty to retreat in Wyoming?
As a general rule, no—not when you are lawfully present and meet the justification statute or case-law standard. Fact-specific exceptions (initial aggressor, unlawful activity, co-occupant disputes) still matter.
Does justified self-defense block civil lawsuits in Wyoming?
Wyoming does not offer as broad a statutory civil-immunity shield as some stand-your-ground states. Even a strong criminal self-defense claim can leave civil exposure depending on the facts and causes of action.
