Apollos "Paul" Smith (1825–1912) was an American hunting and fishing guide from Vermont who founded the Saint Regis House in the Town of Brighton, New York, in the Adirondack Mountains. It was known universally as Paul Smith's Hotel, one of the first wilderness resorts in the Adirondacks. In its day, it was the most fashionable of the many great Adirondack hotels, patronized by American presidents, celebrities, and the power elite of the latter half of the 19th century. It was a large operation, with 255 rooms, stables, and many other amenities.
