Kellogg’s Star Wars-themed breakfast cereal introduced in 1984 was called C-3PO’s.
The cereal was marketed in the United States during the period surrounding Return of the Jedi. Its name and packaging used C-3PO, the golden protocol droid played by Anthony Daniels, as its central character. The product was shaped as small letter C pieces, creating a visual connection with the character’s name.
C-3PO’s is often confused with later Star Wars food promotions, including branded cereals and snacks released for newer films. It was a Kellogg’s product, not a General Mills cereal. The cereal also belongs to the early-1980s wave of licensed Star Wars merchandise that extended well beyond toys, games, and trading cards.
The character’s name includes the numeral 3, so the cereal’s title is conventionally written “C-3PO’s,” rather than “C-3POs” or “C-3PO cereal.”
