Achiote, or Achiotl, (Bixa orellana) is a shrub or small tree from the tropical regions of the Americas, also known also by its Tupi name of urucum. It is cultivated there and in Southeast Asia, where it was introduced by the Spanish in the 17th century. It is best known as the source of the natural pigment annatto, produced from the fruit. The plant bears pink flowers and bright red spiny fruits which contain red seeds. The fruits dry and harden to brown capsules.

The inedible fruit is harvested for its seeds, which contain annatto, also called bixin. It can be extracted by stirring the seeds in water. It is used to color food products, such as cheeses, fish, and salad oil. It is a main ingredient in the Mexican spice mixture recado rojo, or "achiote paste". The seeds are ground and used as a nearly flavorless but colorful additive in Jamaican and Filipino cuisine. Annatto is growing in popularity as a natural alternative to synthetic food coloring compounds.

The achiote has long been used by American Indians to make body paint, especially for the lips, which is the origin of the plant's nickname, lipstick tree. Parts of the plant can be used to make medicinal remedies for such conditions as sunstroke, tonsilitis, burns, leprosy, pleurisy, apnoea, rectal discomfort, and headaches.
