Sticker Emblem of the city of Tel Aviv, Israel

Tel Aviv-Yafo (Hebrew: תֵּל אָבִיב-יָפוֹ, romanized: Tēl ʾĀvīv-Yāfō or Hebrew: תֵּל אָבִיב־יָפוֹ, romanized: Tēl ʾĀvīv-Yāfō, IPA: [tel aˈviv jaˈfo]; Arabic: تَلّ أَبِيب – يَافَا, romanized: Tall ʾAbīb-Yāfā), sometimes rendered as Tel Aviv-Jaffa, and usually referred to as just Tel Aviv, is the most populous city in the Gush Dan metropolitan area of Israel. Located on the Israeli Mediterranean coastline and with a population of 495,600, it is the economic and technological center of the country and a global high-tech hub. If East Jerusalem is considered part of Israel, Tel Aviv is the country's second-most-populous city, after Jerusalem; if not, Tel Aviv is the most populous city, ahead of West Jerusalem. Tel Aviv is governed by the Tel Aviv-Yafo Municipality, headed by Mayor Ron Huldai, and is home to most of Israel's foreign embassies. It is a beta+ world city and is ranked 53rd in the 2022 Global Financial Centres Index. Tel Aviv has the third- or fourth-largest economy and the largest economy per capita in the Middle East. Tel Aviv is ranked the 4th top global startup ecosystem hub. The city currently has the highest cost of living in the world. Tel Aviv receives over 2.5 million international visitors annually. Tel Aviv is home to Tel Aviv University, the largest university in the country with more than 30,000 students. The city was founded in 1909 by the Yishuv (Jewish residents) and initially given the Hebrew name Ahuzat Bayit (Hebrew: אחוזת בית, lit. 'House Estate' or 'Homestead'), namesake of the Jewish association which established the neighbourhood as a modern housing estate on the outskirts of the ancient port city of Jaffa (Yafo in Hebrew), then part of the Mutasarrifate of Jerusalem within the Ottoman Empire. Its name was changed the following year to Tel Aviv, after the biblical name Tel Abib (lit. "Tell of Spring") adopted by Nahum Sokolow as the title for his Hebrew translation of Theodor Herzl's 1902 novel Altneuland ("Old New Land"). Other Jewish suburbs of Jaffa had been established before Tel Aviv, the oldest among them being Neve Tzedek. Tel Aviv was given township status within the Jaffa Municipality in 1921, and became independent from Jaffa in 1934. Immigration by mostly Jewish refugees meant that the growth of Tel Aviv soon outpaced that of Jaffa, which had a majority Arab population at the time. In 1948, the Israeli Declaration of Independence was proclaimed in the city, with Tel Aviv named as the founding capital of Israel – a function it retained officially until 1950. After the 1947–1949 Palestine war, Tel Aviv began the municipal annexation of parts of Jaffa, fully unified with Jaffa under the name Tel Aviv in April 1950, and was formally renamed to Tel Aviv-Yafo in August 1950. Tel Aviv's White City, designated a UNESCO World Heritage Site in 2003, comprises the world's largest concentration of International Style buildings, including Bauhaus and other related modernist architectural styles. Popular attractions include Old Jaffa, the Eretz Israel Museum, the Museum of Art, Yarkon Park, and the city's promenade and beach.
