#3. Ric Flair - 1993-1994 (289 days)
"The Nature Boy" Ric Flair held sixteen World Championships in total and the majority of them came in WCW. Flair's final two WCW World title reigns only lasted a combined eight days but his earlier runs with the title lasted much longer.
None lasted longer than his second reign with the gold.

It began at Starrcade 1993 in December of that year, when he upended Vader in a classic encounter and lasted all the way to Bash at the Beach in July 1994, when he was defeated by the debuting, Hulk Hogan in a heavily hyped bout. In between those two bookends, Flair defended the strap in memorable encounters versus Vader, Ricky "The Dragon" Steamboat and Barry Windham.
Flair's title run was one of the best of his career and perhaps his swansong as a world-class World Champion. It was only surpassed in length by two other reigns and one other performer.
