The Sharon Plain is the northern half of the coastal plain of Israel. Its largest city is Netanya.

The Plain lies between the Mediterranean Sea to the west and the Samarian Hills, 15 kilometres (9.3 mi) to the east. It stretches from Haifa and Mount Carmel in the north to the Yarkon River in the south, at the edge of the present city of Tel Aviv, about 90 kilometres (56 mi). Parts of the Plain are included in the Haifa, Center, and Tel Aviv Districts of Israel. In 2008 The Sharon Plain was home to 1,131,600 people[1], 965,300 of them (85.3%) are Jews, and 166,300 (14.6%) are Arabs.

The Plain of Sharon is mentioned in the Bible. In ancient times, the plain was particularly fertile and populous. Zionist immigrants arrived in the early twentieth century, and populated the region with many settlements.[2] In 2008, it was the most densely populated region of Israel.[
