Abstract. While a broad debate on carceral geographies has been part of human geography and related disciplines in English-speaking academia, there are only scarce publications among German-speaking geographers. This special issue aims at bringing different researchers (Tobias Breuckmann, Julia Emprechtinger, Sarah Klosterkamp, Nadine Marquardt, Marco Nocente, Marina Richter and Anna Schliehe) and their rich and diverse research insights in the carceral field into a dialogue. What started with a session at the 2019 conference of German-speaking geography (Deutscher Kongress für Geographie), developed into a special issue that encompasses papers based on the contributions to the session as well as additional papers that round up the insights into current research in carceral geographies in German-speaking countries. The papers show the importance of applying a carceral geography perspective to research in German-speaking geography to focus on different institutions, places and spaces that share common carceral characteristics. In addition, the focus on German-speaking researchers also adds to the international debate on carceral geographies with specific insights from the national contexts.
