William Charles Redfield (March 26, 1789 - February 12, 1857) was an American meteorologist. He was the first president of the American Association for the Advancement of Science (1843).
William Charles Redfield is known in meteorology for his observation of the directionality of winds in hurricanes  (being among the first to propose that hurricanes are large circular vortexes, though John Farrar had made similar observations six years earlier), though his interests were varied and influential.
Redfield organized and was a member of the first expedition to Mount Marcy in 1837; he was the first to guess that Marcy was the highest peak in the Adirondacks, and therefore in New York. Mount Redfield was named in his honor by Verplanck Colvin. He was elected an Associate Fellow of the American Academy of Arts and Sciences in 1845.
At a meeting of the American Association for the Advancement of Science, in 1854, Redfield mentioned a storm-path in which no less than seventy odd vessels had been wrecked, dismasted, or damaged.
