The United Nations (UN) International Migrants Day is annually held on December 18 to recognize the efforts, contributions, and rights of migrants worldwide.

On December 4, 2000, the UN General Assembly, taking into account the large and increasing number of migrants in the world, proclaimed December 18 as International Migrants. On that day, a decade earlier, the assembly adopted the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families. Earlier celebrations of the day can be traced as far back as 1997 when some Asian migrant organizations marked December 18 as the day to recognize the rights, protection, and respect for migrants.
