The Jackson's chameleon (Trioceros jacksonii) is a species of chameleon native to the mountainous forests of East Africa, particularly in Kenya and Tanzania. They are also known as three-horned chameleons due to the presence of three prominent horns on the heads of males—one on the nose and two above the eyes. Females usually lack these horns or have much smaller ones.
