Nightingale secured the win with a backslide pin despite interference from Skye Blue.
The title win earns her a defense against Owen Hart Cup winner Mercedes Moné at AEW All In at Wembley Stadium on August 30.
During the July 29 episode of AEW Dynamite, Moné interrupted Nightingale's championship celebration.
The crowd responded with loud chants before AEW World Tag Team Champions Divine Dominion joined Moné in attacking Nightingale.
The Brawling Birds intervened to stop the assault.
Speaking at the post-show media scrum, Nightingale reflected on her journey. "Fascinating thing about this too is that has all been accomplished within this year.
I won the TBS Title two years ago for the first time, but I held the Tag and TBS earlier this year.
Now this, the World Title," she said.
"It's really a whirlwind.
I love AEW because, now, it feels a lot more like we've got our legs, we're more established.
But it still feels so exciting and new," Nightingale added. "Like this is the beginning of something so much more.
In my head, I'm like, 'This is gonna go on and on and this is still like we're just getting started.'
And to be somebody who is kind of helping lay down that foundation, and hitting these marks and achievements at such a crazy, awesome time… I'm beside myself.
