Welf I

{{Short description|Swabian nobleman}} {{for|the Duke of Bavaria|Welf I, Duke of Bavaria}} {{inline|date=March 2024}}{{onesource|date=March 2024}} '''Welf I''' or '''Welfo''' (died before 876) was a Swabian nobleman. He was a member of the Elder House of Welf.

Welf was probably a son of Conrad I of Auxerre, and seems to have taken over his father's offices in Swabia, namely: count of Alpgau, count of Linzgau, and possibly count of Argengau. However, when Conrad and his other sons changed allegiance from King Louis the German to his half-brother King Charles the Bald in 859, Welf disappears from the historical record. It is assumed that he fell out of favor with King Louis and lost his offices; the Swabian branch of the Elder Welfs was not mentioned again until Rudolf II, Count of Altdorf, who died around 990 and was — according to legend — a descendant of Welf.
