The 2005 Final Resolution was a professional wrestling pay-per-view (PPV) event produced by Total Nonstop Action Wrestling (TNA), which took place on January 16, 2005 from the Impact Zone in Orlando, Florida. It was the first annual event under the Final Resolution chronology. Nine matches were featured on the event's card.

The main event was a standard wrestling match for the NWA World Heavyweight Championship, in which the champion, Jeff Jarrett, defeated the challenger, Monty Brown to retain the championship. The TNA X Division Championship was contested in an Ultimate X match, in which A.J. Styles defeated Chris Sabin and the champion, Petey Williams. The event's undercard featured different varieties of matches. America's Most Wanted (Chris Harris and James Storm) defeated Team Canada (Bobby Roode and Eric Young) for the NWA World Tag Team Championship on the undercard. Monty Brown defeated Diamond Dallas Page and Kevin Nash in a Three Way Elimination match to challenge Jeff Jarrett for the NWA Championship in the main event.

The professional wrestling section of the Canadian Online Explorer website rated the entire event an 8 out of 10, which was higher than the 2006 event's rating.

In October 2017, with the launch of the Global Wrestling Network, the event became available to stream on demand.
