Louis Seymour, known as "French Louie" or "Adirondack French Louie" (c. 1832–February 28, 1915) was an Adirondack guide, trapper, woodsman and hermit. His age was unknown but his death certificate said he was 84. He was born near Ottawa Canada, sometime around 1832. French Louie is mentioned in virtually every book written about the South-Central Adirondacks. A lot of what is known of him is from the oral tradition, but Harvey Dunham wrote a biography in 1953.
