ROH/NJPW War of the Worlds (2014)

War of the Worlds was a professional wrestling supershow co-produced by the American Ring of Honor (ROH) and Japanese New Japan Pro-Wrestling (NJPW) promotions. The event took place on May 17, 2014, at the Hammerstein Ballroom in New York City, New York, U.S. and aired live on Internet pay-per-view (iPPV) through Ustream.

All matches on the iPPV featured wrestlers from ROH taking on wrestlers from NJPW. As a result, bookers from both promotions worked together to put the event together. The event featured nine matches with five championships on the line; three from ROH and two from NJPW. In the only title change, reDRagon (Bobby Fish and Kyle O'Reilly) regained the ROH World Tag Team Championship from The Young Bucks (Matt and Nick Jackson). The event was headlined by a double main event for the top titles from both promotions. In the first, Adam Cole successfully defended the ROH World Championship against Jyushin Thunder Liger and in the second A.J. Styles successfully defended the IWGP Heavyweight Championship in a three-way match with Kazuchika Okada and Michael Elgin.
