Jo Collins (birthname Janet Canoy, born August 5, 1945 in Lebanon, Oregon) was Playboy magazine's Playmate of the Month for December 1964 and Playmate of the Year for 1965. Her original pictorial was photographed by Mario Casilli.
She was nicknamed “G.I. Jo” for her United Service Organizations tours to Vietnam to entertain the troops during the Vietnam War. In 1966, during one of those tours, she delivered a lifetime subscription to Playboy to Second Lieutenant John Price.
In December 1979 Jo posed nude for the "Playmates Forever!" pictorial.
