Paul Fitzpatrick Russell (born May 2, 1959) is an American prelate of the Catholic Church who was appointed auxiliary bishop of the Archdiocese of Detroit in May 2022.

Wanting to learn Spanish, he traveled to Peru and Bolivia with the St. James Society, spending a year in South America.

[3] After his 1987 ordination, the archdiocese assigned Russell as an associate pastor to Sacred Heart Parish in West Lynn, Massachusetts.

In 1992, shortly after arriving at a new assignment at St. Eulalia Parish in Winchester, Massachusetts, Law asked Russell to become one of his priest-secretaries.

[1] On July 1, 1997, Russell entered the diplomatic service,[4] serving first for a short while in Rome working with Bishop James Harvey.

[3] On May 23, 2022, Pope Francis named Russell as an auxiliary bishop of Detroit, allowing him to keep the personal title of archbishop.

"[1] Russell has a devotion to his mother's cousin Michał Piaszczyński, a beatified priest who died in the Sachsenhausen concentration camp during World War II.
