Brigham Young University (BYU), located in Provo, Utah, United States, is a private, coeducational research university owned by The Church of Jesus Christ of Latter-day Saints (LDS or Mormon Church). It is the oldest existing institution within the LDS Church Educational System. It is also America's largest religious university, and has the third-largest private university enrollment in the United States. Approximately 98% of the 34,000 students at BYU are members of the LDS Church; one-third of its American students come from within the state of Utah.

BYU students are required to follow an honor code, which mandates behavior in line with LDS teachings (e.g., academic honesty, adherence to dress and grooming standards, and abstinence from extramarital sex and from the consumption of drugs and alcohol). Approximately 97% of male BYU graduates have taken a two-year hiatus from their studies at some point to serve as Mormon missionaries, and 32% of BYU female graduates have been missionaries as well. Many BYU students obtain a level of foreign language proficiency while serving as LDS missionaries, and BYU has many foreign language classes, offering courses in over 70 languages. Over 75% of BYU students have some foreign language proficiency.

The university's primary focus is on undergraduate education, but it also has 68 master's and 25 doctoral degree programs, including a Juris Doctor program. About 70% of student tuition is funded by LDS Church tithing funds, making tuition less expensive than at similar private universities.
