Ayam Cemani is an uncommon and relatively modern breed of chicken from Indonesia. Ayam means "chicken" in Indonesian. Cemani refers to the village on the island of Java where this breed of chicken originated.

They have a dominant gene that causes hyperpigmentation (fibromelanosis), making the chicken entirely black, including feathers, beak, and internal organs.

The breed originated from the island of Java, Indonesia, and have probably been used for centuries for religious and mystical purposes.
