Circuit breaker lockout devices are disclosed that effectively lock one or more circuit breakers in a circuit breaker panel in a safe or open circuit position. Embodiments of the circuit breaker lockout devices are robust, utilize few loose parts, and are easily installed. The devices are also short in profile, thereby allowing them to be installed in a circuit breaker panel having minimal clearance between the circuit breakers and a closed panel door cover.
