Roger Sablonier (16 April 1943 – 8 June 2010) was a Swiss historian and writer of non-fiction publications, and Emeritus (Prof. Dr.) of the faculty of the University of Zürich.

From 1984 to 2006, he was an ordained professor at the University of Zürich, and since 2006 Emeritus (Emeritierter Ordinarius für Geschichte des Mittelalters) of the historical faculty.

Roger Sablonier treated the past as a serious matter, but related to the archeology, mischief overcame,[clarification needed] and he used to say to his students: One can dig a hole anywhere in this country, but if you only dig deep enough, it's a safe bet that you'll find any bones [human remains].

Sablonier engaged especially in the current discourse of history and culture in the implementation of the historical and scientific research, also in exhibitions and museums, and oversaw the reorganization of the archives of the Einsiedeln Abbey.

Priorities of Roger Sablonier's research and publication were the history of nobility, the rural society of the late European Middle Ages, the political culture of the Old Swiss Confederacy, and in writing.
