Aaron David Gordon (June 9, 1856 – February 22, 1922), more commonly known as A. D. Gordon, is a Zionist ideologue and the spiritual force behind practical Zionism and Labor Zionism.
He founds Hapoel Hatzair, a movement that sets the tone for the Zionist movement for many years to come.
Influenced by Leo Tolstoy and others, it is said that in effect he made a religion of labor.
However, he himself writes in 1920, "Surely in our day it is possible to live without religion."
