Marcus Helvécio Martins (born 22 April 1959)[1] is the former dean and department chair for religious education at Brigham Young University–Hawaii (BYU–Hawaii), and also the author of Setting the Record Straight: Blacks and the Mormon Priesthood.

Martins then went to Provo, Utah, where he studied for six years at Brigham Young University (BYU), earning degrees in business management, organizational behavior, and a Ph.D. in Sociology.

His research focuses on temple symbolism, and the impact of globalization forces, technology, and immigration on the growth of the LDS Church, as well as consequences of the doctrines of the restoration on daily religiosity.

In 1978, Marcus Martins became engaged to Mirian Abelin Barbosa, who had just returned from serving in the church's Brazil São Paulo South Mission.

Over the years, Martins has served in the LDS Church twice as a bishop (in Brazil and Hawaii), seven times as a high councilor, and as a temple ordinance worker, among other positions.
