Vicki Reamy Baker was paddling in Silver Springs State Park, Florida, when she was approached by the huge reptile.
In videos shared on Facebook, Vicki can be seen gently pushing the gator away from her with her paddle, prompting it to hiss.
A voice over a loudspeaker then said: "Mam, I would suggest backing up after you just made him pretty mad."
Keeping remarkably calm - to say there is a massive alligator lurking next to her - Vicki spoke to the creature like it was a pesky pigeon.
She said: "What are you doing? Get away from me, get away from me... Why are you messing with me. Why are you trying to bite me?"
Writing on Facebook after the frightening encounter, she speculated that someone had been feeding the animal.
She wrote: "Gator tried to eat my board. Someone has been feeding him and made him very dangerous. He was a big boy."
He certainly was, Vicki.
Believe it or not, encounters with gators are a part of life in Florida.
Last month, TikTok user Jade - or @capecoral.jade - uploaded a clip she filmed while out fishing with a group of friends in the Everglades.
Jade was filming one of her friends who was standing with a fishing line in the water and seemed to be attempting to find an alligator they had seen previously.
Jade asked, 'Where did he go?' as she zoomed in on the water.
However, she was then left horrified when she realised the alligator was just feet away from her, camouflaged by the water.
At this point, Jade - understandably - let out a scream and yelled to her pals: "Oh my god, holy s**t."
While another member of the group added: "That's why you do not ever sit down with your legs in the water."
Jade replied: "I'm not kidding, I almost s**t myself."
Posting the clip, Jade wrote: "Florida Everglades never fails to amuse and terrify."
And fellow TikTok users were quick to agree.
Commenting on the clip, one person said: "I was watching that screaming 'it's right there!' like y'all can hear me."
Another wrote: "That gator could have jumped and bit you in 0.5 seconds. You're very lucky."
While a third person advised: "Y'all have to assume that every body of water in Florida might have gator in it. Stay safe."
