Charles John Huffam Dickens (; 7 February 1812 – 9 June 1870) was an English novelist, journalist, short story writer and social critic. He created some of literature's best-known fictional characters, and is regarded by many as the greatest novelist of the Victorian era. His works enjoyed unprecedented popularity during his lifetime and, by the 20th century, critics and scholars had recognised him as a literary genius. His novels and short stories are widely read today.

Born in Portsmouth, Dickens left school at age 12 to work in a boot-blacking factory when his father John was incarcerated in a debtors' prison. After three years, he returned to school before beginning his literary career as a journalist. Dickens edited a weekly journal for 20 years; wrote 15 novels, five novellas, hundreds of short stories and nonfiction articles; lectured and performed readings extensively; was an indefatigable letter writer; and campaigned vigorously for children's rights, education and other social reforms.

Dickens's literary success began with the 1836 serial publication of The Pickwick Papers, a publishing phenomenon—thanks largely to the introduction of the character Sam Weller in the fourth episode—that sparked Pickwick merchandise and spin-offs. Within a few years, Dickens had become an international literary celebrity, famous for his humour, satire and keen observation of character and society. His novels, most of them published in monthly or weekly instalments, pioneered the serial publication of narrative fiction, which became the dominant Victorian mode for novel publication.
