Rodolph is an uncommon, yet distinctive given name of German origin. It is derived from the Germanic elements hrod, meaning "fame," and wulf, which translates to "wolf." The name gained popularity during the Middle Ages in Europe but has since become quite rare. Rodolph was once a popular royal name, with several European monarchs bearing this title throughout history. Today, it is more often found as a surname than a given name.
