Art Clokey (born Arthur Farrington, October 12, 1921, Detroit, Michigan) is a pioneer in the popularization of stop motion clay animation, beginning in 1955 with a film experiment called Gumbasia, influenced by his professor Slavko Vorkapich at the University of Southern California.

When Clokey was 9 years old, his parents divorced and he stayed with his father. After his father died in a car accident, he went to live with his mother in California, but was placed in a half-way house orphanage after one year because his stepfather did not want him around. At age 12, he was adopted by Joseph W. Clokey, a classical music composer and organist who taught music at Pomona College in Claremont, California, and who encouraged young Arthur's artistic inclinations. The aesthetic environment later became the home of Art Clokey's most famous character, Gumby, whose name derives from Art Clokey's childhood experiences during summer visits to his grandfather's farm, when he enjoyed playing with the clayey mud called "gumbo."

At Webb School in Claremont, young Clokey came under the influence of teacher Ray Alf, who took students on expeditions digging for fossils and learning about the world around them. Clokey later studied geology at Pomona College, where he received his undergraduate degree in 1943.

Beginning in 1955, Gumby has been a familiar presence on television, appearing in several series—and even in a 1995 feature film, Gumby: The Movie. Clokey's second most famous production is the duo of Davey and Goliath, funded by the Lutheran Church.

Art Clokey also made a few highly experimental and visually inventive short clay animation films for adults, including his first film Gumbasia, the visually rich Mandala—described by Clokey as a metaphor for evolving human consciousness—and the equally bizarre The Clay Peacock, an elaboration on the animated NBC logo of the time. These films have only recently become available via the Rhino box-set release of Gumby's television shorts, all appearing on the bonus DVD (disc 7).

Clokey is also credited with the bizarre clay-animation title sequence for the beach movie Dr. Goldfoot and the Bikini Machine (1965), starring Vincent Price and Frankie Avalon.

His son, Joe Clokey, continued the Davey and Goliath cartoon in 2004.

In March 2007, KQED broadcast an hour-long documentary "Gumby Dharma" as part of their Truly CA series.

In 2007, Princeton Architectural Press published an interview between Art Clokey and Dorian Devins (illustrated by Glenn Head) in "The Best of LCD (Lowest Common Denominator): The Art and Writing of WFMU" edited by Dave the Spazz.
