Niemotko v. Maryland, 340 U.S. 268 (1951), was a case in which the Supreme Court of the United States held that the city of Havre de Grace, Maryland had violated the free exercise of Niemotko's religion by not issuing a permit for him and his religious group (the Jehovah's Witnesses) to meet in a public park when other religious and civic groups had been given permits for holding their meetings there.
