For its first 76 years, it was called the "Diocese of Great Falls" (Latin: Dioecesis Great-Ormensis). Bishop Thomas J. Murphy changed the name of the diocese on February 14, 1980, adding "Billings" (and also changing the way that "Great Falls" was translated into Latin).
The co-patrons of the diocese are:
- Saint Matthias, whose feast day is May 14, from the patron saint of the first bishop
- Saint Pius X, whose feast day is August 21, since this saint, while pope, erected the diocese
- Mathias Clement Lenihan (1904–1930), originally from Dubuque, Iowa.
- Edwin Vincent O'Hara (1930–1939), from Portland, Oregon.
- William Joseph Condon (1939–1967), from Spokane, Washington.
- Eldon Bernard Schuster (1967–1977), from Great Falls, Montana.
- Thomas Joseph Murphy (1978–1987), from Chicago, Illinois.
- Anthony Michael Milone (1987–2006), from Omaha, Nebraska.
- Michael William Warfel (2007–present), from Elkhart, Indiana.
