Founding 3 Doors Down vocalist Brad Arnold died Saturday at the age of 47 “after a courageous battle with cancer,” the American rock band announced.

“He passed away peacefully, surrounded by loved ones, in his sleep after his courageous battle with cancer,” the band shared in a statement.

Back in May 2025, the singer announced his stage 4 kidney cancer diagnosis on Instagram, which led 3 Doors Down to back out of their anticipated Summer of ‘99 tour with Creed, Finger Eleven and others.

"I got some not good news for you today," Arnold said as he began a video posted to the band's Instagram. "I was sick a couple of weeks ago, and I went to the hospital and got checked out, and actually got the diagnosis that I had clear cell renal carcinoma that had metastasized to my lung, and it's stage 4 and that's not real good."

Clear cell renal carcinoma is the most common type of kidney cancer; however, it is quite aggressive and easily spreads, according to the National Institute of Health.

Formed in Mississippi in 1996, 3 Doors Down is one of the mainstay rock bands of the late ‘90s and early 2000s, with mega rock hits “Kryptonite”, “When I’m Gone”, and “Here Without You”, among others, living in the brains of countless millennials and those older.

The band's statement in full reads:

With heavy hearts, we share the news that Brad Arnold, founder, lead singer, and songwriter of 3 Doors Down, passed away on Saturday, February 7th, at the age of 47.

With his beloved wife Jennifer and his family by his side, he passed away peacefully, surrounded by loved ones, in his sleep after his courageous battle with cancer.

As a founding member, vocalist, and original drummer of 3 Doors Down, Brad helped redefine mainstream rock music, blending post-grunge accessibility with emotionally direct songwriting and lyrical themes that resonated with everyday listeners. Brad's songwriting became a cultural touchstone for a generation, producing some of the most enduring hits of the 2000s, including the band's breakout hit, "Kryptonite," which he wrote in his math class when he was just 15 years old. His music reverberated far beyond the stage, creating moments of connection, joy, faith, and shared experiences that will live on long after the stages he performed on.

Above all, he was a devoted husband to Jennifer, and his kindness, humor, and generosity touched everyone fortunate enough to know him. Those closest to him will remember not only his talent, but his warmth, humility, faith, and deep love for his family and friends.

The family is deeply grateful for the outpouring of love and support during this difficult time and kindly asks that their privacy be respected.

He will be deeply missed and forever remembered.
