Achziv or Az-Zeeb is an ancient site on the Mediterranean coast of northern Israel, between the border with Lebanon and the city of Acre. It is located 13.5 kilometres (8.4 mi) north of Acre on the coast of the Mediterranean Sea, within the municipal area of Nahariya. Today it is an Israeli national park.

As of 2015, Israel maintains 81 national parks and more than 400 nature reserves, many of them in the occupied West Bank, that protect 2,500 species of indigenous wild plants, 32 species of fish, 530 species of birds and 100 species of mammals.
