Police responded to calls to a medical emergency at Berry's home in Buckner Road, just outside his birthplace of St Louis, at around 12.40pm (5.40pm GMT) on Saturday.
Paramedics tried to administer "lifesaving techniques" but he could not be revived.
A police spokeswoman said: "The St Charles County Police Department sadly confirms the death of Charles Edward Anderson Berry Sr, better known as legendary musician Chuck Berry.
"The family requests privacy during this time of bereavement."
Born in St Louis in October 1926, Berry attempted to emulate his musical heroes including Nat King Cole and Muddy Waters, according to the biography on his Facebook page.
At high school his first stage performance, of a Jay McShann song called Confessin' The Blues, received a "thunderous applause", the bio said.
He went on to become a celebrated musician, known for his energetic stage presence and his signature move - a one-legged hop called a "duck walk".
Many of his songs, including Johnny B Goode, Maybellene and Memphis, have been much covered and taught to many a budding young guitarist.
In 1984 he was presented with a Grammy Award lifetime achievement prize and was among the first to be inducted into the Rock and Roll Hall of Fame in 1986.
He was still touring as recently as 2014 and his website heralds his first new album in 38 years, which reportedly includes new material, as coming "soon".
He leaves behind his wife Themetta Suggs-Berry, who he met a year after his release from prison in 1947, and four children.
Daughter Ingrid Berry-Clay and son Charles Berry Jr both performed alongside their father as members of his band.
A statement on Berry's Facebook page said he was a "beloved" husband, father, grandfather and great-grandfather.
It added: "Though his health had deteriorated recently, he spent his last days at home surrounded by the love of his family and friends.
"The Berry family asks that you respect their privacy during this difficult time."
The Kinks' frontman, Sir Ray Davies, said: "Without Chuck Berry there would have been no roll to rock to.
"His lyrical rhythmic landscapes and vocal style inspired me to write and gave me the belief that I could perform my own work. He is one of America's great poets."
