A Jurassic Park-like beast interrupted some golfers during an outing in Florida on Wednesday ... and video of the reptile crawling around the course is WILD!!!

Check out some footage that golfers in Naples shot this week ... you can see the gator -- roughly 10 FEET LONG -- was just cruising through tee boxes without a care in the world.

"Holy ...," one golfer said while seeing the animal on the course. "This guy out for a stroll -- oh, my God!"

Gators haven't been shy about making appearances on golf courses over the past year ... remember when two beasts brawled on an 18th hole in South Carolina?

Also, who could forget the gator that stole some dude's ball in Louisiana!!!
