Roman Reigns (118 Days)
Despite being the company’s golden boy (and a three-time WWE Champion), Reigns has only held the title for 113 days. His first reign ended with the infamous “Sheamus 5:15”, and his 2nd one was just a little over a month long. He lost his title in the Royal Rumble, but he won it back in one of the most panned main events in Wrestlemania history.
His 3rd and most recent reign ended after a measly 77 days. He probably would have held it longer had he not gotten suspended. Alas, he lost to Seth Rollins, who lost it to Ambrose, and the rest is history.
It’s really crazy to think that Jinder Mahal is champion longer than Reigns ever was, but these things happen.
