Travis Kelce better prep his monologue ... 'cause "Saturday Night Live" alum Taran Killam tells TMZ Sports the NFL superstar would be the perfect pick to host the comedy sketch show!!
"Travis Kelce is one of the funniest, coolest dudes and a legend," Killam said at LAX.
"It's just not fair to be that strong, fast, good, charismatic, handsome and hilarious. I hate him. He's coming for my job," he joked (or is he?)
Killam knows about both comedy and football -- he actually has an Amazon Prime show, "The NFL Pile On," where he puts a funny twist on the sport's biggest stories of the week.
Killam has spent a ton of time at 30 Rock -- he was on "SNL" from 2010-2016 ... and had several memorable sketches during his stint.
Killam even thinks Kelce could take his talents to acting if he really wanted ... and says if "SNL" were to come calling, he'd thrive as the celebrity host for an episode.
"I'd love to see Travis Kelce host," Killam said, swallowing his pride as a Rams fan. "I think he'd kill it."
Someone get Lorne Michaels on the phone!!
