Fredrick Martin Jannetty (born February 3, 1960) is an American professional wrestler who has worked for promotions including the World Wrestling Federation/Entertainment (WWF/E), the American Wrestling Association (AWA), World Championship Wrestling (WCW) and Extreme Championship Wrestling (ECW), and has won a total of 20 championships.

Jannetty is widely known for his tenure as half of tag team The Rockers, in which he partnered with Shawn Michaels. The duo originally found success during the mid-to-late 1980s under the moniker of The Midnight Rockers, becoming two-time AWA World Tag Team Champions and winning various regional titles. They became one of the foremost teams of the WWF's "Golden Age", headlining multiple events. The Rockers held the WWF World Tag Team Championship in late 1990, but their reign was voided for disputed reasons.

After splitting from Michaels in early 1992, Jannetty became a one-time WWF Intercontinental Champion and a one-time WWF World Tag Team Champion with the 1-2-3 Kid. He competed in multiple world championship matches between ECW and the WWF from 1995–1996, but Jannetty's star faded thereafter, and he was largely used as enhancement talent during a late 1990s run in WCW. He made sporadic appearances for WWE during the latter half of the 2000s (including a brief 2005 reunion with Michaels), and has remained a challenger for titles on the independent circuit.

Although his career was continually halted by personal issues and his achievements overshadowed by those of Michaels, Jannetty was described by Talksport as being "as smooth and jaw-dropping as his partner, with a drop-kick to rival any".
