If This Is a Man is a memoir by Jewish Italian writer Primo Levi, first published in 1947. It describes his arrest as a member of the Italian anti-fascist resistance during the Second World War, and his incarceration in the Auschwitz concentration camp (Monowitz) from February 1944 until the camp was liberated on 27 January 1945.

A memoir is any nonfiction narrative writing based on the author's personal memories. The assertions made in the work are thus understood to be factual. While memoir has historically been defined as a subcategory of biography or autobiography since the late 20th century, the genre is differentiated in form, presenting a narrowed focus, usually a particular time phase in someone's life or career. A biography or autobiography tells the story "of a life", while a memoir often tells the story of a particular career, event, or time, such as touchstone moments and turning points in the author's life. The author of a memoir may be referred to as a memoirist or a memorialist.
