The Gifford Lectures are lectures established by the will of Adam Lord Gifford (d. 1887). They were established to "promote and diffuse the study of Natural Theology in the widest sense of the term - in other words, the knowledge of God." They are given at Scottish universities: Edinburgh_University, University_of_Aberdeen, University_of_St_Andrews, and University_of_Glasgow.

Notable Gifford lectures include those by William James, published as "The Variety of Religious Experience," and those by Albert Schweitzer, published as "The Search for the Historical Jesus." Other famous Gifford lecturers include Alfred North Whitehead, Reinhold Niebuhr, Niels Bohr, Arnold J. Toynbee, Iris Murdoch, and Stanley Hauerwas.
