Lambert of Maastricht was a 7th-century bishop who served the see of Maastricht-Liège from approximately 670 until his death around 705. Born into a noble family in Maastricht, he was educated by the archpriest Landoald and later rose to his episcopal position following the death of his predecessor, Theodard. During a period of intense political transition between the Merovingian and Carolingian dynasties, Lambert became a victim of the era's violent power struggles. He is remembered as a martyr for his refusal to remain silent regarding the illicit relationship of Pepin of Herstal.
