Missing Link was a retrospective sports program that aired on the American network ESPN Classic. It debuted on March 7, 2007 and aired every Wednesday night at 10 p.m. Eastern time and was hosted by the host of ESPN Radio's The Herd, Colin Cowherd.

Missing Link is best described as a version of Six Degrees of Kevin Bacon involving famous athletes, coaches, and other sports figures. Each end of the chain is seemingly the exact opposite of the other in some way, but are somehow connected. The length of each chain varies between five and seven names. In a television-worthy twist, one end is connected, then the other, with a middle link revealed only at the end, following a commercial break.

Missing Link was pre-empted on April 25 for a replay of the heavyweight boxing championship match between Lennox Lewis and Frank Bruno, but the show returned the following week, amidst a blog report that indicated that ESPN Classic would halt all original programs. It was then quietly dropped again two weeks later and did not return. ESPN Classic now fills the hour once taken up by Missing Link with various programs like Who's No. 1?.
