On April 11, 2014, Danielson married WWE wrestler Brie Bella, with whom he had been in a relationship for nearly three years.
On April 6, 2016, nearly two months after Danielson's retirement, Bella also semi-retired from wrestling in order to start a family with him.
They have a daughter named Birdie Joe Danielson (born May 9, 2017).On August 1, 2020 Brie gave birth to their second child, a boy.

In 2009, Danielson relocated to Las Vegas, Nevada, where he began training in MMA at Randy Couture's Xtreme Couture gym.
He was also roommates with Xtreme Couture's head grappling trainer, Neil Melanson.

Danielson became a vegan in 2009 after suffering from elevated liver enzymes and several staph infections.
In 2012, he was awarded a Libby Award from PETA for being the Most Animal-Friendly Athlete.
That same year, Mayor Micah Cawley of Yakima, Washington declared January 13 "Daniel Bryan Day".
Later that year, Danielson explained that he was no longer a vegan due to his inability to find vegan food while traveling with WWE.
He later elaborated that he had developed a soy intolerance and could not find enough non-soy vegan food, but he still keeps a mostly vegan diet on the road.
In 2018, it was reported that both he and his wife are vegetarians.
Danielson has stated that he has vitiligo.

In October 2012, a social media campaign was started in an attempt to help Connor Michalek meet Danielson, his personal hero.
Michalek was six years old at the time and suffered from cancer of the brain and spine.
The campaign succeeded, with Danielson meeting Michalek at the Consol Energy Center in December 2012 and again in October 2013.

Danielson is a self-described environmentalist and endorsed Green Party nominee Jill Stein in the 2016 United States presidential election.

Danielson is a fan of the Seattle Seahawks, and wore Seahawks inspired ring gear at SummerSlam 2018.
