Aliyah (US /ˌæ.lɪ.ˈɑː/, UK /ˌɑː.li.ˈɑː/; Hebrew: עֲלִיָּה‎ aliyah, "ascent") is the immigration of Jews from the diaspora to the Land of Israel (Eretz Israel in Hebrew). Also defined as "the act of going up"—that is, towards Jerusalem—"making Aliyah" by moving to the Land of Israel is one of the most basic tenets of Zionism. The opposite action, emigration from the Land of Israel, is referred to in Hebrew as yerida ("descent"). The State of Israel's Law of Return gives Jews and their descendants automatic rights regarding residency and Israeli citizenship.

For much of Jewish history most Jews have lived in the diaspora where aliyah was developed as a national aspiration for the Jewish people, although it was not usually fulfilled until the development of the Zionist movement in the late nineteenth century. The large-scale immigration of Jews to Palestine began in 1882. Since the establishment of the State of Israel in 1948, more than 3 million Jews have moved to Israel. As of 2014, Israel and the Palestinian territories together contain 42.9% of the world's Jewish population.
