This conceptual article brings to the attention of tourism scholars new possibilities to theorize dark tourism as an affective socio-spatial encounter. To do so, we frame dark tourism within theories of affect and, in particular, geographies of affect. We show how debates around dark tourism terminology and taxonomies, in most cases underlie considerations on felt, affective aspects of the dark tourism experience. We critically debate the concept of affect, the distinctions between affects and emotions, and the complex issue of representability of affect. Our perspective is underpinned by a necessity to consider the context and limitations that frame the affective experience of the tourist and the resulting encounters. This offers a deeper layer of understanding tourists' experiences in death and disaster places as well as the political and ethical charge imbued in such encounters.
