This is a list of high school athletic conferences in the East and Southeast Regions of Ohio, as defined by the OHSAA.^[1] Because the names of localities and their corresponding high schools do not always match and because there is often a possibility of ambiguity with respect to either the name of a locality or the name of a high school, the following table gives both in every case, with the locality name first, in plain type, and the high school name second in boldface type. The school's team nickname is given last.

All schools are also affiliated with the Ohio Valley Athletic Conference.

1. Ross County schools that were concurrent in SVC and Ross County League from date of SVC entrance until 1975.

Formed in 1970 as the Adams County League, Brown County League, and Highland County League merged to provide a stable schedule after consolidation decimated all three. The league has an odd distinction in that all of its current members were league members by its second year, giving the SHAC a level of continuity that most rural-based leagues do not have.
