The Sapphire City is the capital of the Ozure Isles, in Lake Orizon in the Munchkin Country of Oz. In the opinions of Princess Ozma, Dorothy Gale, Betsy Bobbin, Trot, and others, the Sapphire City is second only to the Emerald City as the fairest city of Oz.

Just as the Emerald City is characterized by its emeralds, so the Sapphire City is dominated by the blue light of its distinctive jewels. The City contains a noteworthy sapphire tower; its silver bells toll the hours. The garden of the king's castle includes an enchanted tree that bears a single golden pear at a time. Eating the pear generates a powerful pair of magic gold wings on the eater's back. (The Giant Horse of Oz)
