The Office of the United Nations High Commissioner for Refugees (UNHCR) is a United Nations agency mandated to aid and protect refugees, forcibly displaced communities, and stateless people, and to assist in their voluntary repatriation, local integration or resettlement to a third country. It is headquartered in Geneva, Switzerland, and has 20,305 staff.

As of June 2020, UNHCR has over 20 million refugees under its mandate. Consequently, its annual budget has grown from US$300,000 in 1951 to US$8.6 billion in 2019, making it one of the largest UN agencies by expenditure. The vast majority of UNHCR's budget comes from voluntary contributions, mostly from member states; the largest donors are the United States, the European Union, and Germany. The agency's work includes providing protection, shelter, healthcare and emergency relief, assisting in resettlement and repatriation, and advocating for national and multilateral policies on behalf of refugees.

According to a 2021 study, the UNHCR has fulfilled its mandate to serve refugees independent of their location consistently over time. The organization has shown limited bias towards donors in the geographical distribution of its funds.
