Oyama v. State of California, 332 U.S. 633 (1948), was a case in which the United States Supreme Court decided that specific provisions of the 1913 and 1920 California Alien Land Laws abridged the rights and privileges guaranteed by the Fourteenth Amendment to Fred Oyama, a citizen of the United States in whose name his father, who held Japanese citizenship, had purchased land. In doing so, however, the court did not overturn the California Alien Land Laws as unconstitutional.
