Asher Zvi Hirsch Ginsberg (August 18, 1856 –January 2, 1927), primarily known by his Hebrew name and pen name, Ahad Ha'am, (Hebrew: lit. one of the people, Genesis 26:10), is a Hebrew essayist, and one of the foremost pre-state Zionist thinkers.

He is known as the founder of cultural Zionism.

With his secular vision of a Jewish "spiritual center" in Palestine, he confronts Theodor Herzl.

Unlike Herzl, the founder of political Zionism, Ha'am strives for "a Jewish state and not merely a state of Jews".
