What is the name of the fictional prison in Stephen King's The Green Mile?

The fictional prison in Stephen King’s The Green Mile is Cold Mountain Penitentiary.

The novel’s main action takes place on the prison’s death row in 1932. Paul Edgecombe is the block supervisor there, and he narrates the story years later from a nursing home. The death-row corridor is nicknamed “the Green Mile” because of its green linoleum floor and its grim role as the prisoners’ final route to the electric chair.

Cold Mountain is the setting where Paul meets John Coffey, an unusually large inmate convicted of murdering two children. Coffey displays mysterious healing abilities, which drive the novel’s supernatural and moral questions. Other prisoners, including Eduard Delacroix and William “Wild Bill” Wharton, also shape the story.

Readers sometimes mistake the prison for Shawshank State Prison, another famous Stephen King setting. Shawshank appears in “Rita Hayworth and Shawshank Redemption,” while Cold Mountain belongs specifically to The Green Mile. The book was first published as six monthly installments in 1996 before appearing as a single volume.
