Regarding the Pain of Others is a 2003 book-length essay by American writer Susan Sontag, which was nominated for the National Book Critics Circle Award.

Sontag regarded the book as a sequel to her 1977 essay collection On Photography and reassessed some of the views she held in the latter.

Using photography as evidence for her opinions, Sontag sets out to answer one of the three questions posed in Virginia Woolf's book Three Guineas, "How in your opinion are we to prevent war?"

While challenging a certain number of common ideas concerning images of pain, horror, and atrocity (including some to which she contributed), Regarding the Pain of Others both underscores their importance and undercuts hopes that they can communicate very much.

On the one hand, narrative and framing confer upon images most of their meaning, and on the other, Sontag says, those who have not lived through such things "can't understand, can't imagine" the experiences such images represent.
