Michelle Duppong (1984–2015) was an American Catholic missionary and laywoman known for her vibrant faith, dedication to evangelization, and joyful witness to Christ. Born and raised on a farm in North Dakota, Michelle grew up in a loving Catholic family and developed a deep devotion to her faith. After earning a degree in horticulture from North Dakota State University, she felt called to serve God by bringing others closer to Him. She joined the Fellowship of Catholic University Students (FOCUS) as a missionary, serving on college campuses to inspire young adults to embrace their faith and live Christ-centered lives.

During her six years with FOCUS, Michelle worked tirelessly to mentor students, lead Bible studies, and build meaningful relationships rooted in faith. Her joyful spirit, compassion, and authenticity left a lasting impression on those she encountered. In 2012, she returned to her home diocese to serve as the Director of Adult Faith Formation for the Diocese of Bismarck, continuing her mission to lead others to Christ. Michelle's humility, humor, and unwavering trust in God's plan were hallmarks of her life and ministry.

In 2014, Michelle was diagnosed with a rare form of cancer. Despite her illness, she remained a source of inspiration, offering her suffering for the salvation of souls and trusting completely in God’s will. Michelle passed away on Christmas Day in 2015 at the age of 31, leaving a legacy of faith, hope, and love. Her life continues to inspire many, and in 2022, the Diocese of Bismarck opened her cause for canonization.
