Arothron meleagris, commonly known as the guineafowl puffer or golden puffer, is a pufferfish from the Indo-Pacific, and Eastern Pacific. It is occasionally caught for the aquarium trade. It reaches 50 centimetres (20 in) in length.

Guineafowl puffers have heavy rounded bodies that are uniformly black with numerous small white spots (black puffer or botete negro), bright yellow spots (golden puffer or botete dorado) or a mixture of the two morphologies with bright yellow spots and black patches. They have large blunt heads with short snouts and are equipped with a set of massive teeth. They have small and similarly shaped anal and dorsal fins that are well back on their body. Their caudal fin base is long and deep and their caudal fin is rounded. Their body is covered with small denticles that resemble coarse sandpaper. When this fish is scared or frightened, they inflate and make themselves larger, exposing the denticles.
