Modern Hebrew (endonym: עִבְרִית חֲדָשָׁה, romanized: 'Ivrit ḥadasha, IPA: [ivˈʁit χadaˈʃa] or [ʕivˈrit ħadaˈʃa]), also known as Israeli Hebrew or simply Hebrew, is the standard form of the Hebrew language spoken today. It is the only extant Canaanite language, as well as one of the oldest languages to be spoken as a native language in the modern day, on account of Hebrew being attested since the 2nd millennium BC. It uses the Hebrew Alphabet, an abjad script written from right-to-left. The current standard was codified as part of the revival of Hebrew in the late 19th and early 20th centuries, and now serves as the sole official and national language of the State of Israel, where it is predominantly spoken by over 10 million people. Thus, Modern Hebrew is nearly universally regarded as the most successful instance of language revitalization in history.

A Northwest Semitic language within the Afroasiatic language family, Hebrew was spoken since antiquity as the vernacular of the Israelites until around the 3rd century BCE, when it was supplanted by a western dialect of the Aramaic language, the local or dominant languages of the regions Jews migrated to, and later Judeo-Arabic, Judaeo-Spanish, Yiddish, and other Jewish languages. Although Hebrew continued to be used for Jewish liturgy, poetry and literature, and written correspondence, it became extinct as a spoken language.

By the late 19th century, Russian-Jewish linguist Eliezer Ben-Yehuda had begun a popular movement to revive Hebrew as an everyday language, motivated by his desire to preserve Hebrew literature and a distinct Jewish nationality in the context of Zionism. Soon after, a large number of Yiddish and Judaeo-Spanish speakers were murdered in the Holocaust or fled to Israel, and many speakers of Judeo-Arabic emigrated to Israel in the Jewish exodus from the Muslim world, where many would adapt to Modern Hebrew.

Currently, Hebrew is spoken by over 10 million people, counting native, fluent, and non-fluent speakers. Over 6.5 million of these speak it as their native language, the overwhelming majority of whom are Jews who were born in Israel. The rest is split: 2 million are immigrants to Israel; 1.5 million are Israeli Arabs, whose first language is usually Arabic; and half a million are expatriate Israelis or diaspora Jews.

Under Israeli law, the organization that officially directs the development of Modern Hebrew is the Academy of the Hebrew Language, headquartered at the Hebrew University of Jerusalem.

The most common scholarly term for the language is "Modern Hebrew" (עברית חדשה). Most people refer to it simply as "Hebrew" (עברית Hebrew pronunciation: [ivˈʁit]).

The term "Modern Hebrew" has been described as "somewhat problematic" as it implies unambiguous periodization from Biblical Hebrew. Haiim B. Rosén [he] (חיים רוזן) supported the now widely used term "Israeli Hebrew" on the basis that it "represented the non-chronological nature of Hebrew". In 1999, Israeli linguist Ghil'ad Zuckermann proposed the term "Israeli" to represent the multiple origins of the language.

The history of the Hebrew language can be divided into four major periods:
