Jedediah Peck (January 28, 1748 – August 15, 1821) was an American farmer, surveyor, Revolutionary War soldier, and New York State legislator described as a father of the common school system of the State of New York. He was a man of limited education and had no gift as a debater or speaker, but he was a skillful organizer. (His first name has occasionally been spelled Jedidiah or Jedadiah in the literature.)
