Adolf is a given name used in German-speaking countries, Scandinavia, the Netherlands and Flanders, France, Italy, Spain, Portugal and to a lesser extent in various Central European and East European countries with non-Germanic languages, such as Lithuanian Adolfas and Latvian Ādolfs. Adolphus can also appear as a surname, as in John Adolphus, the English historian. The female forms Adolphine and Adolpha are far more rare than the male ones.
