The name Robert is an ancient Germanic given name, from Proto-Germanic *hrōþiz "fame" and *berhtaz "bright" (Hrōþiberhtaz). Compare Old Dutch Robrecht and Old High German Hrodebert (a compound of Hruod (Hróðr) "fame, glory, honour, praise, renown" and berht "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert.
After becoming widely used in Continental Europe, the name entered England in its Old French form Robert, where an Old English cognate form (Hrēodbēorht, Hrodberht, Hrēodbēorð, Hrœdbœrð, Hrœdberð, Hrōðberχtŕ) had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto.
Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be used as a French, Polish, Irish, Finnish, Romanian, and Estonian name as well.
The name Robert was a royal name in France, Germany, Scotland and England during the medieval period, and was the name of several kings, dukes, and other rulers and noblemen. It was one of the most popular male names in medieval Europe, likely due to its frequent usage amongst royalty and nobility. To this day, Robert remains one of the most frequently given male names.
Robert was in the top 10 most given boys' names in the United States for 47 years, from 1925 to 1972. While some names become less frequently used due to negative associations, Robert is still widely used despite its connection to many negatively evaluated historical figures.
