Massive Multiplayer Online Wargame Leveraging the Internet (MMOWGLI) was an online multiplayer game used by the US Navy Office of Naval Research and other U.S. government agencies to perform online wargames in order to study various problems and hypothetical scenarios.

MMOWGLI was launched by ONR and the Naval Postgraduate School in order to blend gaming and social media tools and to crowdsource solutions.

It was initially launched with an application addressing a piracy scenario off the coast of Somalia.

The idea received coverage from national news media.
