War of the Worlds (2016) was a professional wrestling tour co-produced by the American Ring of Honor (ROH) and Japanese New Japan Pro-Wrestling (NJPW) promotions. The tour's three events took place on May 9 at the Ford Community & Performing Arts Center in Dearborn, Michigan, May 11 at the Ted Reeve Arena in Toronto, Ontario and May 14 at Terminal 5 in New York City, New York. The second night in Toronto was taped for four episodes of Ring of Honor Wrestling. 2016 was the third year in which ROH and NJPW co-produce events under the War of the Worlds name.

In February 2014, the American Ring of Honor (ROH) promotion announced a partnership with the Japanese New Japan Pro-Wrestling (NJPW) promotion, which led to the two co-producing the Global Wars and War of the Worlds events in Toronto and New York City, respectively, the following May. A year later, the partnership continued with War of the Worlds '15 and Global Wars '15, which were both two-day events, taking place in Philadelphia and Toronto, respectively. On August 21, 2015, representatives of NJPW and ROH declared that the relationship between the two promotions was stronger than ever, announcing another North American tour for May 2016, featuring new locations and wrestlers, as well as the first co-produced shows between the two promotions in Tokyo. The two-day event, entitled Honor Rising: Japan 2016, took place on February 19 and 20, 2016.
