What is the title of the final published Chronicles of Narnia book?

The Last Battle is the final published book in C.S. Lewis’s Chronicles of Narnia.

The Last Battle was published in 1956 and concludes the seven-book Narnia series. The story concerns a false Aslan, political conflict in Narnia, and the final destruction of the world. It brings together themes and characters from earlier books while presenting a final transition into a new reality known as the true Narnia.

Lewis received the Carnegie Medal for The Last Battle in 1957. The award recognized it as the outstanding children’s book of the previous year. The novel’s ending has generated substantial discussion because it uses religious imagery and presents a sharply divided account of judgment, loss, and renewal.

The book’s position can be confused with its internal chronology. The Magician’s Nephew describes events at the beginning of Narnia’s history but was published earlier than The Last Battle and is often numbered first in chronological reading editions. The Last Battle remains the final installment in both publication sequence and narrative conclusion.
