Vicente Liem de la Paz was an 18th-century Dominican friar and priest from Tonkin, located in present-day northern Vietnam. Born into a noble Christian family in Nam Định, he traveled to the Philippines to study at the University of Santo Tomas and Colegio de San Juan de Letran. After joining the Dominican Order and being ordained, he returned to his homeland to serve as a professor at a seminary. He is recognized as the first Vietnamese Christian martyr, having been executed by beheading following a trial by the King.
