Pippin the Younger (c. 714 – 24 September 768), often known under the mistranslation Pippin the Short (French: Pépin le Bref; German: Pippin der Kleine), was a King of the Franks from 751 until his death. He was the first of the Carolingians to become King.

The younger son of the Frankish prince Charles Martel, Pepin's upbringing was distinguished by the ecclesiastical education he had received from the monks of St. Denis. Succeeding his father as the Mayor of the Palace in 741, Pepin reigned over Francia jointly with his elder brother Carloman. Pepin ruled in Neustria, Burgundy, and Provence, while his brother Carloman established himself in Austrasia, Alemannia and Thuringia. The brothers were active in subjugating revolts led by the Bavarians, Aquitanians, Saxons, and the Alemanni in the early years of their reign. In 743, they ended the Frankish interregnum by choosing Childeric III, who was to be the last Merovingian monarch, as figurehead king of the Franks.

Being well disposed towards the church and Papacy on account of their ecclesiastical upbringing, Pepin and Carloman continued their father's work in supporting Saint Boniface in reforming the Frankish church, and evangelising the Saxons. After Carloman, who was an intensely pious man, retired to religious life in 747, Pepin became the sole ruler of the Franks. He suppressed a revolt led by his half-brother Grifo, and succeeded in becoming the undisputed master of all Francia. Giving up pretense, Pepin then forced Childeric into a monastery and had himself proclaimed king of the Franks with support of Pope Zachary in 751. The decision was not supported by all members of the Carolingian family and Pepin had to put down a revolt led by Carloman's son, Drogo, and again by Grifo.
