Sephardic or Sephardi Jews (Hebrew: יהדות ספרד, romanized: Yahadut Sefarad, transl. Jewry of Hispania; Ladino: Djudíos Sefardíes), also Sephardim or Hispanic Jews, are a Jewish diaspora population associated with the Iberian Peninsula. The term, which is derived from the Hebrew Sepharad (lit. 'Spain'), can also refer to the Mizrahi Jews of Western Asia and North Africa, who were also influenced by Sephardic law and customs. Many Iberian Jewish exiles also later sought refuge in Mizrahi Jewish communities, resulting in integration with those communities.

The Jewish communities of the Iberian Peninsula prospered for centuries under the Muslim reign of Al-Andalus following the Umayyad conquest of Hispania, but their fortunes began to decline with the Christian Reconquista campaign to retake Spain. In 1492, the Alhambra Decree by the Catholic Monarchs of Spain called for the expulsion of Jews, and in 1496, King Manuel I of Portugal issued a similar edict for the expulsion of both Jews and Muslims. These actions resulted in a combination of internal and external migrations, mass conversions, and executions. By the late 15th century, Sephardic Jews had been largely expelled from Spain and scattered across North Africa, Western Asia, Southern and Southeastern Europe, either settling near existing Jewish communities or as the first in new frontiers, such as along the Silk Road.

Historically, the vernacular languages of the Sephardic Jews and their descendants have been variants of either Spanish, Portuguese, or Catalan, though they have also adopted and adapted other languages. The historical forms of Spanish that differing Sephardic communities spoke communally were related to the date of their departure from Iberia and their status at that time as either New Christians or Jews. Judaeo-Spanish, also called Ladino, is a Romance language derived from Old Spanish that was spoken by the eastern Sephardic Jews who settled in the Eastern Mediterranean after their expulsion from Spain in 1492; Haketia (also known as "Tetuani Ladino" in Algeria), an Arabic-influenced variety of Judaeo-Spanish, was spoken by North African Sephardic Jews who settled in the region after the 1492 Spanish expulsion.

In 2015, more than five centuries after the expulsion, both Spain and Portugal enacted laws allowing Sephardic Jews who could prove their ancestral origins in those countries to apply for citizenship; while the Spanish law that offered expedited citizenship to Sephardic Jews expired in 2019, the Portuguese law was effectively ended for new applicants in 2022.
