The California Alien Land Law of 1913 prohibits "aliens ineligible for citizenship" (i.e. all Asian immigrants) from owning land or property, but permits three year leases. It affected the Chinese, Indian, Japanese, and Korean immigrant farmers in California. It passed thirty-five to two in the Senate and seventy-two to three in the Assembly and was co-written by assemblyman and later attorney general Ulysses S. Webb.

It was invalidated in 1946 by the Supreme Court of California as a violation of the equal protection clause of the 14th Amendment to the United States Constitution in the case of Sei Fujii v. California.
