Bob Weir, the guitarist and co-founder of the Grateful Dead, has died at age 78 after battling cancer and succumbing to underlying lung issues. His family confirmed the news on January 10, 2026, noting that he passed peacefully surrounded by loved ones. Tributes from fellow musicians and celebrities have poured in, celebrating his enduring legacy in American music.
Bob Weir, born Robert Hall Weir on October 16, 1947, in San Francisco, was adopted and raised in the Bay Area suburb of Atherton. Struggling with undiagnosed dyslexia, he was expelled from several schools before picking up the guitar at age 13. On New Year's Eve 1965, he met Jerry Garcia at Dana Morgan's Music Store in Palo Alto, leading to the formation of the Mother McCree's Uptown Jug Champions, which evolved into the Warlocks and then the Grateful Dead in 1965.
As the band's rhythm guitarist and co-lead vocalist alongside Garcia, Weir's syncopated style, influenced by jazz pianist McCoy Tyner's left hand, became a cornerstone of the Grateful Dead's improvisational sound. The band released their debut album in 1967 and Live/Dead in 1969, capturing their extended jams. Weir contributed key songs like "Playing in the Band," "One More Saturday Night," and "Cassidy," and released his solo debut Ace in 1972. Over six decades, the Grateful Dead performed more than 2,300 concerts, sold over 35 million albums, and pioneered the jam band genre.
Following Garcia's death in 1995, Weir continued with projects like RatDog, Furthur, and Dead & Company, which included Mickey Hart, Bill Kreutzmann, and John Mayer. Their final shows were a three-night stand at San Francisco's Golden Gate Park in August 2025, marking the band's 60th anniversary. Diagnosed with cancer in July 2025, Weir began treatment weeks before those performances, which his family described as "emotional, soulful, and full of light."
Weir's family statement read: "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." They emphasized his role in building a "community, a language, and a feeling of family" for generations of fans. In 2017, Weir became a United Nations Goodwill Ambassador for climate change efforts.
Tributes flooded in: TV host Andy Cohen called Weir "impossibly beautiful and wildly fiery"; Eagles guitarist Don Felder remembered seeing him at Woodstock; Sonic Youth's Lee Ranaldo shared lyrics from "Sugar Magnolia"; Billy Corgan wrote "God Bless Bob Weir"; and Slash posted a heartfelt photo. Weir's family, including Natascha, Monet, and Chloe, requested privacy amid the outpouring of support.
