Vicente Liem de la Paz, Vietnamese: Vinh Sơn Lê Quang Liêm (1732 - November 7, 1773) was a Tonkinese (present day northern Vietnam) Dominican friar venerated as a saint and martyr by the Roman Catholic Church. He was born at Tra-lu, Tonkin in 1732 to Antonio and Monica Daeon de la Cruz, members of the Tonkinese nobility. When he fell gravely ill several days after his birth, he was baptized by Fr. Chien de Santo Tomas, taking the name of Vicente Liem de la Paz. Since Tra-lu was one of those Tonkinese villages where Dominican friars preached the Catholic faith, Liem grew up to be a Christian. He was later brought by his parents to a missionary center where he learned catechism.

In 1738, King Philip V of Spain opened the Colegio de San Juan de Letran and the University of Santo Tomas in the Philippines to Chinese and Tonkinese students, since China and Tonkin did not have Christian educational institutions. The Dominican fathers decided to let Liem with four other Tonkinese (Jose de Santo Tomas, Juan de Sto. Domingo, Pedro Martir and Pedro de San Jacinto) study in the Philippines.

Vicente took the trivium and the quadrivium in Colegio de San Juan de Letran, now the equivalent of elementary and secondary education. He finished a degree of lector of humanities at Letran. He would pursue his collegiate education at the University of Santo Tomas while residing at Letran. In September 1753, after completing his studies at UST, he entered the Dominican order, along with his four Tonkinese companions. A year later, they made their solemn professions. On January 28, 1755, he received the tonsure and minor orders at the Church of Sta. Ana. In 1758, de la Paz was ordained priest under the Dominican order. On September of that year, he passed the examinations to hear confessions. On October 3, he started his journey back to Tonkin. He arrived on January 20, 1759.
