The Heart of America Athletic Conference (the Heart) is a college athletic conference affiliated with the NAIA. Member institutions are located in Iowa, Kansas, Missouri, and Nebraska in the United States.
The HAAC's earliest ancestor was the Missouri College Athletic Union, which was formed in 1924 when the Missouri Intercollegiate Athletic Association (now the Mid-America Intercollegiate Athletics Association) split in two. The old MIAA's private schools formed the Athletic Union, while the state teachers' colleges stayed in the MIAA It was reorganized as the HAAC in 1971 when it began admitting schools outside Missouri. However, the HAAC does not presently claim the Athletic Union's history as its own.
In early 2014, Grand View University and William Penn University were announced as members for the 2015-16 school year. In April 2015, Clarke University and Mount Mercy University were announced as members for the 2016-17 school year.
The current commissioner of the conference is Lori Thomas. Thomas, the first female commissioner in NAIA history, began her term on July 1, 2014, succeeding Larry Lady who retired after 22 years as commissioner.
