Grand Canyon University (GCU) is a private for-profit Christian university in Phoenix, Arizona. Based on student enrollment, Grand Canyon University was the largest Christian university in the world in 2018, with 20,000 attending students on campus and 70,000 online.Grand Canyon was established by the Arizona Southern Baptist Convention on August 1, 1949, in Prescott, Arizona, as Grand Canyon College. In 1999–2000, the university ended its affiliation with the Southern Baptist Convention. Suffering financial and other difficulties in the early part of the 21st century, the school's trustees authorized its sale in January 2004 to California-based Significant Education, LLC, making it the first for-profit Christian college in the United States.
