The Hummingway are a rabbit-like race featured in Final Fantasy IV, Final Fantasy IV -Interlude-, and Final Fantasy IV: The After Years who live in the Hummingway Home on the Red Moon. Most of them can only speak by humming, however, there are a select few that can speak in the player's language.
In the original release of Final Fantasy IV, Hummingway are a short, vaguely lapine race with pointed ears and white or light brown fur. They are usually depicted as sporting a pair of spectacles and wearing turbans inlaid with a round jewel.
Since the Nintendo DS remake, the Hummingway were redesigned by art director Akira Oguro to appear more rabbit-like; with longer ears, buck teeth, and larger eyes. Beginning with the mobile phone release of Final Fantasy IV: The After Years, they were designed yet again to include a hood, a trait originally exclusive to Namingway.
The party encounters the Hummingway after traveling to the Red Moon. Though they do not advance the story, they do provide the only item shop on the lunar surface, as well as give an explanation for Namingway's appearance on Earth. When Cecil and his friends defeat Zeromus at the end of the game, Fusoya pilots the Red Moon out of Earth's orbit, taking the Hummingway away as well.
The Hummingway appear during the The Lunarians' Tale, once again in Hummingway Home. Here, they sell items for Golbez and Fusoya, and provide hints on how to get to both the Lair of the Father and the Lunar Ruins. Hummingways are also encountered on the True Moon.
The rabbit-like appearance of the Namingways and their origins on the moon harken to the myth of the Moon rabbit, a legend that interprets the markings on the moon as a rabbit grinding a mortar and pestle, in some interpretations the rabbit is using them to mix medicines. One legend says that the rabbit came to arrive in the moon when it threw itself into a fire to feed a starving man, and the man revived it and took it to the heavens to honor it for its generosity.
- The names Hummingway and Namingway may be an allusion to the surname Hemingway which is shared by famed American author and journalist Ernest Miller Hemingway.
- Series composer Nobuo Uematsu appears as a Hummingway in the Developer's Office in the PS, GBA, and Japanese SNES versions of Final Fantasy IV. In the DS remake, QA staff member Tomokazu Nakamori appears as "Debuggingway".
