Count Rudolph (or Rudolf) of Ponthieu (died 866) was son of Welf (also Hwelf or Welf I) and brother of Judith of Bavaria, wife of Emperor Louis the Pious. Through Judith's influence her brother Rudolph acquired and became Lay Abbot of the Abbey's of Saint Riquier and Jumieges.

In April 830 Frankish nobility revolted against Emperor Louis in order to "liberate" him from the influence of his wife Judith. Louis was placed under house arrest while Judith and her brothers Rudolph and Count Conrad I of Auxerre were imprisoned in Aquitanian monasteries. The two brothers were later freed when their nephew Charles the Bald assumed the throne.

Rudolph married Hruodun. (Hruodun died in 867.)
