Travis Scott's fans are pushing hard for him to headline next year's Coachella, and even have a petition going to get him on stage this year ... and they're getting a big wave of support.

Following the tragedy at Astroworld, Travis has pulled out of multiple festivals, including Coachella, and while he's opting for a break ... his fans still want him to return to live performances.

The petition that's circulating online is pushing for a Coachella make-good -- they want organizers to commit to Travis being a headliner next year ... OR guarantee Kanye West brings him out as a guest during his set this year.

After 3 days, the petition has almost 70,000 signatures.

Keep in mind, there's another petition out there ... this one started immediately after 10 people died at Astroworld in Houston, and demanded Coachella ban Travis, who, at the time, was rumored to be headlining in the desert. Right now that one has 63,000 signatures and counting.

According to the new petition, many of Trav's fans feel Coachella did him dirty -- it says, "After Coachella unfairly removed Travis Scott for Harry Styles, they need to do the right thing and rebook him immediately."

It also absolves Travis of any wrongdoing in Houston, saying ... "We all know Astroworld tragedy wasn't Travis's fault. Let him get back to performing on the biggest stages!"

As for the potential guest spot with Ye? We do know they have the Kardashian-Jenners in common, and Ye recently thanked Trav for helping him find Chicago's birthday party.

Right now it seems unlikely he'd be up for performing -- especially because he voluntarily bowed out -- but then again, the festival's not until April.
