John Daniel Wild (April 10, 1902 – October 23, 1972) was a twentieth-century American philosopher.
Wild began his philosophical career as an empiricist and realist but became an important proponent of existentialism and phenomenology in the United States.
He received an honorary doctorate from Ripon College and served as visiting professor at the Universities of Chicago, Hawaii, and Washington.
He served as president of the Association for Realistic Philosophy (1949) and the Metaphysical Society of America (1954).
In 1962 Wild, along with William A. Earle, James M. Edie, and others, founded the Society for Phenomenology and Existential Philosophy.
