Xenophobia is hostility, prejudice, fear, distrust or rejection directed toward people perceived as foreigners or outsiders, particularly because of their national origin, foreign status or association with another country or cultural group. The word derives from Greek roots commonly translated as xenos, meaning stranger or foreigner, and phobos, meaning fear.
In contemporary usage, xenophobia generally refers to negative attitudes or behaviour toward foreigners, immigrants or people perceived as foreign, although the exact boundaries of the term vary between academic, political, media and legal contexts. Xenophobia can involve beliefs that outsiders threaten employment, security, culture, social cohesion or national identity, but not every disagreement about immigration policy or national borders is necessarily xenophobic. The concept concerns attitudes or behaviour directed at people because they are perceived as outsiders or foreigners. Xenophobia can occur at interpersonal, institutional and societal levels and can overlap with racism, nationalism, ethnocentrism and cultural prejudice without being identical to any of them.
Xenophobia is closely related to the distinction between ingroups and outgroups. People often organise social identities around communities such as nationality, locality, language or citizenship, and these categories can create boundaries between those perceived as insiders and outsiders. Xenophobia emerges when foreignness becomes a basis for negative evaluation, exclusion or hostility. Perceived cultural distance can intensify this process, particularly when people have limited contact with the group concerned.
However, xenophobia is not simply a natural reaction to difference because attitudes toward outsiders vary substantially across societies, historical periods and individuals. Institutions, media narratives, political rhetoric, economic conditions and personal experiences can influence whether foreign groups are perceived positively, negatively or neutrally. The existence of national borders does not itself constitute xenophobia, and a preference for particular immigration rules is not automatically evidence of xenophobic attitudes. The term should therefore be applied to the relevant attitudes or treatment rather than to every discussion involving foreigners or migration.
Xenophobia can develop through several interacting mechanisms. Perceived economic competition may lead some people to believe that foreigners threaten employment, wages or access to public resources. Concerns about security can produce suspicion toward people associated with countries or groups perceived as threatening. Cultural change can also generate anxiety when established practices, languages or demographic patterns change rapidly. Media coverage can influence which aspects of migration or foreign populations receive attention, particularly when unusual or dramatic events receive disproportionate coverage.
Historical conflicts and national narratives can create inherited perceptions of particular foreign populations. These factors do not automatically produce xenophobia because their effects depend on interpretation, institutional conditions and individual experience. Xenophobic attitudes can also be reinforced when people encounter little information that contradicts negative narratives. Understanding these mechanisms is important because the causes of xenophobia are multifaceted rather than reducible to a single emotion called fear.
Xenophobia overlaps with racism but the concepts are not synonymous. Racism generally involves beliefs, attitudes or systems that categorise people through racialised ideas and assign significance or hierarchy to those categories. Xenophobia focuses more specifically on perceived foreignness or outsider status. A person can experience xenophobia because they are perceived as foreign even if they belong to a population that is not conventionally racialised as a distinct race.
Conversely, racialised minorities who are citizens or long established residents can experience racism without being perceived as foreigners. In practice, the two can overlap because nationality, ethnicity, race, language and migration status are often socially connected. A migrant may be treated as foreign because of nationality while simultaneously being racialised because of appearance or ethnicity. Careful analysis therefore asks whether the relevant basis of hostility is foreign status, racialisation, cultural difference or an interaction among these categories.
Xenophobia can appear through language, social exclusion, harassment, unequal treatment, political mobilisation, institutional practices or violence. At the interpersonal level, it may involve insults, avoidance or hostility toward people perceived as foreign. At institutional levels, practices may disadvantage foreigners or migrants through unequal access or differential treatment, although whether a particular policy constitutes unlawful discrimination depends on the relevant legal framework. Public discourse can also portray foreigners as collectively responsible for social problems, thereby encouraging group based suspicion.
Online environments can amplify xenophobic content because highly emotional material can spread rapidly through sharing and recommendation. At the same time, the internet provides opportunities for migrants and host communities to communicate directly, correct misinformation and develop support networks. Digital technology can therefore facilitate both the transmission and the challenging of xenophobic narratives.
Xenophobia has historical connections with migration, nationalism, war and changing population patterns. States have repeatedly experienced debates about who belongs within the political community and how newcomers should be treated. During periods of war or political crisis, foreign nationals may be viewed with heightened suspicion because of perceived links to enemy states. Economic downturns can also increase competition narratives, while rapid migration can become a focus of public debate.
Historical analysis shows that the groups labelled foreign are not fixed because citizenship, borders and national identities change over time. People who were once considered outsiders can become established members of a society, while political changes can redefine who is legally or culturally regarded as foreign. Xenophobia should therefore be understood within particular historical contexts rather than as a timeless response to migration.
Responses to xenophobia can include education, meaningful intercultural contact, accurate information, anti discrimination protections, community programmes and institutional safeguards. Education can challenge false generalisations and provide historical context concerning migration and cultural change. Direct contact can reduce unfamiliarity when interactions involve cooperation and meaningful social relationships, although contact is not automatically sufficient. Public institutions can establish procedures for reporting harassment and discriminatory treatment, while media organisations can improve contextual reporting about migration and foreign populations.
Communities can create opportunities for migrants and long established residents to participate together in local organisations, schools, workplaces and cultural activities. Effective responses need to distinguish between legitimate policy disagreements and hostility directed at people because they are perceived as foreigners. This distinction allows public debate about migration, citizenship and borders to occur without automatically categorising every policy disagreement as xenophobia.
Xenophobia is therefore a specific form of negative intergroup orientation centred on perceived foreignness or outsider status. It can involve fear, distrust, hostility, exclusion or discriminatory treatment, but the precise manifestation depends on social and historical context. It overlaps with cultural prejudice, racism, ethnocentrism and nationalism while remaining conceptually distinct from each. Xenophobia is not established merely by the existence of national boundaries, immigration controls or disagreement about migration policy.
The relevant issue is whether people are negatively evaluated or treated because they are perceived as foreign or outside the national or cultural community. Understanding this distinction helps explain why xenophobia can affect migrants, foreign nationals and people who are merely perceived as foreign, including citizens whose language, appearance, names or cultural practices lead others to question their belonging.
