American ballet choreographer, a leader of the Joffrey Ballet from its founding in 1956 until 2007.

While serving in the U.S. Coast Guard (1945–48), Arpino met dancer Robert Joffrey (Joffrey, Robert) in Seattle, Wash., and learned dancing in his spare time. Later, after training and performing in New York City, he toured with the Ballet Russe and appeared in Broadway musicals. He helped Joffrey to found the Joffrey Ballet in 1956, and in 1961 he offered his first choreography, Partita for 4 and Ropes. Over the years he became known for his hard, fast, youthful ballets. He became associate director of the company and then its artistic director after the death of Joffrey in 1988. Except for a six-month period in 1990, Arpino continued to hold that position until he became artistic director emeritus on July 1, 2007.
