Radcliffe, who played the boy wizard in the film series, is taking part in the starry lockdown reading initiative Harry Potter At Home.
Eddie Redmayne and Stephen Fry are among the other celebrities involved.
The videos will feature on Rowling’s online hub to help children, parents, carers and teachers through the crisis.
Audio versions will also be available on Spotify.
Each celebrity will read a different section of Harry Potter and the Philosopher’s Stone – known as Harry Potter and the Sorcerer’s Stone in the US.
