Glory by Honor VIII: The Final Countdown was a professional wrestling event promoted by Ring of Honor. It took place on September 26, 2009, at the Manhattan Center in New York, New York. The show was headlined by Bryan Danielson vs. Nigel McGuinness, who were both making their last appearances for ROH before leaving for World Wrestling Entertainment. Danielson would go on to find success in the WWE, however McGuinness' contract had fallen through and he signed with Total Nonstop Action Wrestling. Danielson, who was the first to announce he was signing with WWE, was originally scheduled to face Austin Aries for the ROH World Championship, but the match was later changed when McGuinness also announced he was signing.
