John Hicklin Hall (July 17, 1854 – July 27, 1937) was a politician and attorney in the U.S. state of Oregon. A native of the Portland area, he served in the Oregon House of Representatives in the early 1890s before appointment as the United States District Attorney for Oregon. As the federal prosecutor, he became involved in the Oregon land fraud scandal, in which several high-profile public officials conspired to defraud the government in acquiring land for a private entity. Hall was convicted, but subsequently pardoned, for failing to prosecute some of the participants.
