Alien land laws

Alien land laws were a series of legislative attempts to discourage Asian and other "non-desirable" immigrants from settling permanently in U.S. states and territories by limiting their ability to own land and property. Because the Naturalization Act of 1870 had extended citizenship rights only to African Americans but not other ethnic groups, these laws relied on coded language excluding "aliens ineligible for citizenship" to prohibit primarily Chinese and Japanese immigrants from becoming landowners without explicitly naming any racial group. Various alien land laws existed in over a dozen states. Like other discriminatory measures aimed at preventing minorities from establishing homes and businesses in certain areas, such as redlining and restrictive covenants, many alien land laws remained technically in effect, forgotten or ignored, for many years after enforcement of the laws fell out of practice.

Since the 2020s, some states have passed laws with similar restrictions on agricultural land ownership by citizens or entities from "foreign adversaries," such as the People's Republic of China, citing national security concerns. As of October 2025, approximately 29 states have enacted such legislation.
