Joshua King Ingalls (July 16, 1816 – Mar 3, 1899) was an American inventor, Christian minister,[1] writer and land reformer who influenced contemporary individualist anarchists, despite never self-identifying as one.

He believed that government protection of idle land was the foundational source of all limitations on individual liberty.

Like the individualist anarchists of the United States, Ingalls believed in a form of free-market socialism where "Every man will be rewarded according to his work" and each person was to receive the "...whole product of his labor.

[6] Ingalls first learned of the mutualism of Proudhon through Charles A. Dana's articles titled "European Socialism".

[1] His three main influences were Pierre-Joseph Proudhon, Josiah Warren, and Stephen Pearl Andrews.
