Count Otto Franc von Lichtenstein (1846–November 30, 1903) was a cattle baron, sheriff and judge in the Big Horn Basin region of the U.S. state of Wyoming. Franc was born in Germany as a member of the German nobility. He emigrated to the United States in 1866. After visiting the Big Horn Basin area on a hunting trip in 1877–1878 with Texas Jack Omohundro, he returned the following year and established the Pitchfork Ranch on the upper Greybull River, near the present-day town of Meeteetse. Over the next few decades, he became a powerful cattle baron and political figure in the area.
