The Yorkshire Naturalists' Union is an association of amateur and professional naturalists covering a wide range of aspects of natural history. It is one of United Kingdom's oldest extant wildlife organisations and oldest natural history federation. Its Mycological Committee, founded in 1892, is the oldest permanent organisation dedicated to the study of fungi in Great Britain.

History
The Yorkshire Naturalists' Union was founded in 1861 as the West Riding Consolidated Naturalists' Society. Initially a collaboration of five local natural history field clubs, additional clubs and societies from across Yorkshire continued to join. The association renamed itself the Yorkshire Naturalists' Union in 1876.
Activities
The Yorkshire Naturalists' Union organises joint field trips, co-operates with the British Association for the Advancement of Science and other county-sized associations, and publishes a journal, The Naturalist. The journal was first published by the Yorkshire Naturalists' Union in August 1878.
