Kendell Foster Crossen was an American pulp fiction and science fiction writer. He was the creator and writer of stories about the Green Lama and the Milo March detective and spy novels.

The Green Lama is a fictional pulp magazine hero of the 1940s, created by American author Kendell Foster Crossen. He is commonly portrayed as a powerful Buddhist Lama, dressing in green robes with a red scarf and using his powerful skill set to fight crime. Slightly different versions of the same character also appeared in comic books and on the radio. Unlike many contemporary characters from smaller publishers, the Green Lama character is not in the public domain, as the author "wisely retained all rights to his creation".
