N. Eldon Tanner Building, Educational building at Brigham Young University in Provo, Utah, United States.

The N. Eldon Tanner Building is a seven-story, 120,000-square-foot granite structure on the Brigham Young University campus in Provo, Utah. It houses classrooms, professors' offices and administrative offices for the Marriott School of Business. A 76,000-square-foot addition was dedicated in 2008.

Construction began in 1980 under BYU president Dallin H. Oaks and was completed in 1982, with official dedication occurring in 1983. A subsequent expansion project in 2008 significantly enlarged the facility by adding substantial floor space.

The building is named for N. Eldon Tanner, a Canadian politician and counselor to four LDS Church presidents, whom administrators say was known in Canada as "Mr. Integrity" — a title the Marriott School wishes upon each of its graduates. The Marriott School of Business holds classes, faculty offices and administration here.

The building sits on the BYU campus in Provo, Utah, at coordinates 40.25040, -111.65300. Its seven floors and 120,000 square feet hold Marriott School classrooms, professors' offices and administration, plus a 76,000-square-foot addition dedicated in 2008. Floor-to-ceiling glass walls now line the atrium perimeter, installed after the 2018 fall.

The building is named for N. Eldon Tanner, a Canadian politician and counselor to four LDS Church presidents; administrators say he was known in Canada as "Mr. Integrity", a title they wish on every Marriott School graduate. The 2008 addition cost $43 million and was funded by donations.
