Johannah had been cared for at University College London hospital since May before being moved to the Royal Hallamshire Hospital in Sheffield for the last few weeks of her life.
In a statement issued by Louis's representative, her family said: "It is with immeasurable sadness that Johannah Deakin's family said goodbye to Johannah in the early hours of Wednesday 7th December 2016.
"Earlier this year Johannah was diagnosed with a very aggressive form of leukaemia that required immediate and continuous treatment. We respectfully request that the family are given time and space to grieve in private."
Her husband, Dan Deakin, paid tribute, calling her "incredibly selfless" and a "truly amazing mother".
As well as 24-year-old Louis, she leaves behind six other children, Lottie, 18, Felicite, 16, and two sets of twins, Phoebe and Daisy, 12, and two-year-olds Ernest and Doris.
In a 2012 interview, Louis said he and his mother were "best friends".
She was born Johannah Poulston on March 25, 1973.
In 1991, aged 18, she and first husband Troy Austin welcomed the future pop singer into the world.
After the pair divorced when he was a toddler, she married Mark Tomlinson.
The couple had four children but split up as One Direction found X Factor fame.
Two years ago, she married Mr Deakin and gave birth to a second set of twins.
She became a grandmother for the first time in January when Louis's son Freddie Reign was born to Los Angeles-based stylist Briana Jungwirth.
