The Feather Hill Zoo or Feather Hill Ranch Zoo was a U.S. private animal collection in Montecito, California owned by Christian R. Holmes from 1924 to 1930. Featherhill Ranch was located on East Valley Road "astride Romero Creek." Originally a poultry operation, the ranch rapidly established a large collection of birds and animals to attract customers to the site.

Christian Rasmus Holmes II was an American millionaire heir, investor and sportsman. He established the Feather Hill Zoo in California and owned and redeveloped Coconut Island, off the coast of Oahu in Hawaii. He was awarded the Distinguished Service Cross for action during World War I.
