The Monon Athletic Conference (MAC) is an eight-member IHSAA-sanctioned conference in west central Indiana. The conference comprises class 2A and 3A schools from Boone, Clinton, Hendricks, Montgomery, and Putnam counties.

The Monon Athletic Conference set its foundation in 2023 after charter members Crawfordsville, Frankfort, North Montgomery, Southmont, and Western Boone formally separated from the Sagamore Conference (SAC) after the 2024–2025 academic year citing enrollment differences and growth levels between remaining SAC members Danville, Lebanon, and Tri-West. For stability, the conference considered a number of other schools for expansion to bring the league to eight members. North Putnam joined the league from the Western Indiana Conference (WIC) on May 19, 2023. Cascade, which was originally leaving the Indiana Crossroads Conference to re-join the WIC shifted course and joined the MAC on September 26, 2023, thus withdrawing their acceptance back into the WIC. Greencastle followed suit thereafter from the WIC formally following their September 2023 board meeting citing competitive balance and travel distance and costs as the primary reason for moving conferences. These moves collectively take the Sagamore Conference to three members and the Western Indiana Conference to nine members.

The name "Monon Athletic Conference" was introduced on February 22, 2024, following discussions by all league members as all eight members fall on or close to the path of the former Monon Railroad which connected Louisville and Indianapolis to Chicago.
