Divini Redemptoris (Latin for Divine Redeemer) is an anti-communist encyclical issued by Pope Pius XI. It was published on 19 March 1937. In this encyclical, the pope sets out to "expose once more in a brief synthesis the principles of atheistic Communism as they are manifested chiefly in bolshevism". He describes communism as "a system full of errors and sophisms" that "subverts the social order, because it means the destruction of its foundations" as well as removing women from their rightful place in the home.

It was published 5 (9) days after the publication of the more controversial Mit brennender Sorge encyclical that condemned the German Nazi regime and ideology. The timing may have been chosen to try reduce the indignation of the Nazi government against the Catholics in Germany.^{[citation needed]}
