Pepin (French: Pépin; 817 - after 850) was the first count of Vermandois, lord of Senlis, Péronne, and Saint Quentin. He was the son of King Bernard of Italy (a grandson of Charlemagne) and his Queen, Cunigunda of Laon.
Pepin first appears in 834 as a count to the north of the Seine during the reign of his granduncle Louis the Pious, the son and successor to his great-grandfather Charlemagne, aged 17, and then appears again in 840, aged 23. In that year, he supported his 45 year old uncle Lothair I against his aged great uncle, the 62 year old Louis the Pious.
