Regional discrimination in China or regionalism is overt prejudice against people based on their places of origin, ethnicity, sub-ethnicity, language, dialect, or their current provincial zones. China's sheer size and population renders much demographic understanding tied to locality, and there is often little life movement outside of a citizen's province of birth. Historically, internal migration has been tightly controlled, and many barriers to free movement exist today. Treatment of ethnic minorities and Han Chinese regional groups can hinge on preferential assumptions based on places of upbringing, and is often most pronounced towards those born external to urban zones.
When Chinese migrant settle in a new region, local residents can develop social attitudes and prejudgments based on the newcomer's place of birth. If a large volume of new residents relocate from a particular area, regionalism can manifest as sub-ethnic bias and provoke social tension.

As the number and quality of universities vary greatly across China, it is argued that students face discrimination during the admission process based on their region. For example, compared to Beijing, Henan province has fewer universities per capita. Therefore, an applicant in Henan needs a significantly higher score than his Beijing counterpart to attend the same university. This is similar to regional universities in other countries that receive subsidies from regional governments in addition to or in place of the national governments' funding.
