Lepidochitona keepianaIschnochitona keepiana Cyanoplax keepiana, also known as Keep's chiton, is a species of chiton native to the Pacific coast of North America.

[1] According to the Cabrillo Marine Aquarium in San Pedro, Keep's chiton has "brilliant blue markings on its plates that can only be appreciated with a hand lens".

[2] These small chitons, less than an inch long (18 mm), are usually found in fairly warm water in sandy or rocky tide pools located between Cayucos, California,[3] and the Revillagigedo Islands of Mexico.

[4] This species was described to science by S. Stillman Berry in 1948.
