Silicon Wadi (Hebrew: סִילִיקוֹן וָאדִי, lit. 'Silicon Valley') is a region in Israel that serves as one of the global centres for advanced technology. It spans the Israeli coastal plain, and is cited as among the reasons why the country has become known as the world's "start-up nation" (see science and technology in Israel).[1][2] The highest concentrations of high-tech industry in the region can be found around Tel Aviv, including small clusters around the cities of Raʽanana, Petah Tikva, Herzliya, Netanya, Rehovot, and Ness Ziona. Additional clusters of high-tech industry can be found in Haifa and Caesarea. More recent high-tech establishments have been raised in cities such as Jerusalem and Beersheba, in towns such as Yokneam Illit, and in Airport City. Israel has the third highest number of startups by region and the highest rate of startups per capita in the world.[3][4]
