Bob Weir has died.

The 78-year-old guitarist and founding member of the Grateful Dead passed away from "underlying lung issues" on Saturday (01.10.26) just months after being diagnosed with cancer in July 2025.

A statement on his Instagram account said: "It is with profound sadness that we share the passing of Bobby Weir. He transitioned peacefully, surrounded by loved ones, after courageously beating cancer as only Bobby could. Unfortunately, he succumbed to underlying lung issues."

The Grateful Dead reshared the message on Instagram Stories.

The statement went on to share details of his extraordinary career and how he managed to continue working despite undergoing cancer treatment last year.

The message said: "For over sixty years, Bobby took to the road. A guitarist, vocalist, storyteller, and founding member of the Grateful Dead. Bobby will forever be a guiding force whose unique artistry reshaped American music. His work did more than fill rooms with music; it was warm sunlight that filled the soul, building a community, a language, and a feeling of family that generations of fans carry with them. Every chord he played, every word he sang was an integral part of the stories he wove. There was an invitation: to feel, to question, to wander, and to belong.

"Bobby's final months reflected the same spirit that defined his life. Diagnosed in July, he began treatment only weeks before returning to his hometown stage for a three-night celebration of 60 years of music at Golden Gate Park. Those performances, emotional, soulful, and full of light, were not farewells, but gifts. Another act of resilience. An artist choosing, even then, to keep going by his own design. As we remember Bobby, it's hard not to feel the echo of the way he lived. A man driftin' and dreamin', never worrying if the road would lead him home. A child of countless trees. A child of boundless seas.

"There is no final curtain here, not really. Only the sense of someone setting off again. He often spoke of a three-hundred-year legacy, determined to ensure the songbook would endure long after him. May that dream live on through future generations of Dead Heads. And so we send him off the way he sent so many of us on our way: with a farewell that isn't an ending, but a blessing. A reward for a life worth livin'."

Bob is survived by his wife, Natascha, and their two daughters, Shala Monet and Chloe Kaelia.

The statement said: "His loving family, Natascha, Monet, and Chloe, request privacy during this difficult time and offer their gratitude for the outpouring of love, support, and remembrance. May we honor him not only in sorrow, but in how bravely we continue with open hearts, steady steps, and the music leading us home. Hang it up and see what tomorrow brings."
