A golfer was nearly mauled by a monster-sized swan after sinking a putt on a Georgia course this week … and the wild attack was all captured on video!!!

TMZ Sports has learned … John Walters was out on a round with his pals in South Georgia — when the golf outing suddenly turned into a fight with a bird.

You can see in the crazy footage … despite a massive swan parked on the green, Walters went ahead and putted out his 5-footer.

The problem? The made shot had serious ramifications — ’cause the swan attacked!!

The bird nipped at Walters repeatedly, before the dude took off in a full sprint to get away!!

Walters’ daughter tells us the bird has become famous on the course … explaining it lives in a pond near the 9th hole and has a history of being protective of its green and fairway.

It’s unclear what Walters ended up carding on the hole … but yeah, go ahead and insert any eagle/birdie joke you’d like here.
