Albert Kenrick Fisher (21 March 1856 – 12 June 1948) was an American ornithologist, known for his 1893 book The Hawks and Owls of the United States in Their Relation to Agriculture.
To study the role of birds in controlling insect pests, the U. S. Commissioner of Agriculture in July 1885 appointed C. Hart Merriam to create a Branch of Economic Ornithology in the U.S.D.A.
A U.S. Congressional Act of 3 March 1905 enabled the creation on 1 July 1905 of a separate Bureau of Biological Survey.
A list of his papers, complete to 21 March 1926, was published in the Proceedings of the Biological Society of Washington.
He played an important role in the conservation movement and was a personal friend of several famous conservationists, including Gifford Pinchot and Theodore Roosevelt.
