Virtual-NATO is an online flight simulation organization that emulates North Atlantic Treaty Organization (NATO) Military Command flight operations on the Virtual Air Traffic Simulation Network, known as VATSIM.net or "VATSIM".

Virtual-NATO's mission and vision are to simulate military flight operations within a simulated military command structure as closely as possible to the real-world using actual procedures and phraseologies. As such, Virtual-NATO members are serious flight simulator enthusiasts willing to invest the time and effort to conduct online flight operations as close to reality as possible.

Virtual-NATO  pilot training is based on real-world flight training reference material and consists of Primary, Intermediate, Advanced and Mission Qualification flight training phases. The Virtual-NATO  theater of operations encompasses 150 airbases in 29 NATO-countries and a variety of military fighter, airlift, refueling, helicopter, and special operations aircraft.
