St. Andrew Dũng-Lạc was a Vietnamese priest who lived during a period when Christians in Vietnam faced repeated persecution. He was arrested more than once for his faith and continued his ministry despite the danger surrounding the growing Catholic community.

He is remembered together with 117 Vietnamese martyrs — bishops, priests, religious and laypeople who died during persecutions spanning several centuries. Their backgrounds were very different, but the Church honours them together for refusing to abandon their faith even when doing so could have saved their lives.
