Heart of America Athletic Conference

The Heart of America Athletic Conference (HAAC or The Heart) is a college athletic conference affiliated with the National Association of Intercollegiate Athletics (NAIA). Member institutions are located in Iowa, Kansas, Missouri, and Nebraska in the United States.

History
The HAAC's earliest ancestor was the Missouri College Athletic Union (MCAU), which was formed in 1924 when the Missouri Intercollegiate Athletic Association (now the Mid-America Intercollegiate Athletics Association or MIAA) 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 also announced as members for the 2016–17 school year. In October 2019, Park University was approved for HAAC membership and joined in the 2020–21 school year. On February 10, 2022, long-serving Evangel University accepted its invitation to join the Kansas Collegiate Athletic Conference, also Kansas-based, in 2023–24.

On July 24, 2023, William Woods University (alongside St. Ambrose) announced they would join the conference as associate members in football beginning in the 2024 fall season (2024 25 academic year). The expansion made it NAIA's largest football conference with 14 teams playing in two divisions.

The current commissioner of the conference is Lori Thomas. Thomas, the first female commissioner in NAIA history, began her term in 2014, succeeding Larry Lady who retired after 22 years as commissioner.
