Walter is a German and English masculine given name of Germanic origin, composed of the elements meaning "power" or "ruler", and "army".

The name Walter is of Germanic origin composed of the elements walt- (Proto-Germanic *wald-) "power", "ruler", and hari (Proto-Germanic *χarja) "army".^[1]

The name is first recorded in the 6th century, with Walthari son of Wacho, who was king of the Lombards during 539–546. Old Germanic forms are recorded as Walthari, Waltari, Walthar, Waltar, Waltere, Waldheri, Waldhere, Waltheri, Walthere, Walther, Walter, Waldher, and Valter. The Old English equivalent is Wealdhere, Old Norse has Valðar and Valdarr.^[2] It was later used in modern English as Walter.^[3]

The name was popularized by the epic German hero Walther von Aquitaine, and later from the name of the writer Walther von der Vogelweide.^{[citation needed]}

The name entered the French language as Gauthier, Spanish as Gutierre, Portuguese as Gualter and Italian as Gualtiero. The modern Dutch form of the name is Wouter.^{[citation needed]} The German name has also been adopted in a number of languages in the spelling Valter.^{[citation needed]}

Around 2014, the name was most common in Germany, where around 1 in 643 people carried it. 22 percent of them lives in Baden-Württemberg, 16 percent in Bavaria, and 15 per cent in North Rhine-Westphalia.^[4]
