Hoosier Athletic Conference

The Hoosier Athletic Conference is a ten-member Indiana High School Athletic Association -Sanctioned conference located within Benton, Cass, Hamilton, Howard, Jasper, Tippecanoe, Tipton and White counties. The conference first began in 1947, and has been in constant competition except for the 1997–98 school year, when membership dropped to three schools. The conference added four schools from the folding Mid-Indiana Conference in 2015. Lewis Cass exited the conference in 2023 and Logansport was added as the replacement starting in 2024. In 2024 Northwestern will exit the conference filling in for North Miami in the Three Rivers Conference.

Divisions

Former members

Attica played in both the HAC and WRC from 1966 until leaving the HAC in 1971.
Delphi's school board voted to leave the HAC after 2015–16 in November 2015. The school refused to honor the football contracts for 2016–17, so the HAC decided to remove the school from the league effective immediately on December 17, 2015. Since the departure happened in the middle of the school year instead of during the summer, the exit date is listed as 2016, since the school completed the fall season sports as conference members.
Winamac played in both the HAC and NWHC from 1968 to 1972.
Sheridan played in both the HCC and HAC throughout its tenure in the HAC.
Carroll and Clinton Prairie were also members of the Mid-Central Conference from 1966 until 1975.
