Reichsminister (in German singular and plural; 'minister of the realm') was the title of members of the German Government during two historical periods: during the March revolution of 1848/1849 in the German Reich of that period, and in the modern German federal state from 1919 to the end of the National Socialist regime in 1945. The Holy Roman Empire that existed until 1806 did not have a modern government and thus no ministers. In German, the word Reichsminister may refer in rare cases to a minister of a different country, such as a Danish rigsminister or a Dutch rijksminister.
