Blessed James Miller (1944–1982) was an American Christian Brother and missionary who dedicated his life to educating and serving the poor, particularly in Central America. Born in Stevens Point, Wisconsin, he joined the De La Salle Christian Brothers and became a teacher, later serving in Nicaragua and Guatemala. He was known for his dedication to providing quality education and vocational training to impoverished children, especially indigenous youth, while also advocating for human rights in regions affected by political unrest.

During his time in Guatemala, Brother James worked at the La Sallian school in Huehuetenango, where he focused on empowering indigenous students who were often targeted by government forces during the country’s brutal civil war. His commitment to protecting his students and speaking out against oppression made him a target. On February 13, 1982, while repairing a wall at the school, he was shot and killed by three masked gunmen, becoming a martyr for the faith.

Recognized for his courageous witness and sacrifice, Brother James was beatified on December 7, 2019, in Huehuetenango, Guatemala.
