Ohio Southwest Region defunct athletic conferences

This is a list of former high school athletic conferences in the Southwest Region of Ohio, as designated by the Ohio High School Athletic Association. If a conference had members that span multiple regions, the conference is placed in the article of the region most of its former members hail from. 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.

Brown County League

Cincinnati Public League/Interscholastic Athletic Association of Cincinnati

The Interscholastic Athletic Association was founded March 23, 1896, and continued for several years with both public and private high schools until 1931, when it rebranded itself as the Public High School League. Now encompassing solely the public high schools in Cincinnati, the league lasted until 1985, when reshuffling of city and suburban Cincinnati high schools took place, which led to the formation of the Cincinnati Hills League, Eastern Metro Conference, Metro County Conference, and Western Metro Conference.

• Cincinnati Courter Tech Cavaliers (1896–1973, was Cincinnati Tech until 1923, then Central Tech until 1960, school closed)

Clinton County League

This small-school county league is another that hosted members from outside their borders. In this case, Harveysburg from Warren County joined a few years before the conference ended, as the school would merge with three Clinton County schools to become Clinton-Massie. The school would actually be based in Harveysburg until a new school was built near Clarksville, in Clinton County. Blanchester was not included in the 1959–60 standings, due to growing to a AA-sized school by annexing Jefferson, but were allowed back into league play the following season. Blanchester and Clinton-Massie would concurrently play in the CCL and Fort Ancient Valley Conference for the 1964–65 school year, after which the other two CCL schools consolidated into East Clinton, who would join the FAVC nine years later.

Growing from its five initial schools, the conference grew to 11 schools by 1963, but never achieved any sense of stability, as schools joined and left for other conferences throughout its existence.

Paper Valley League

Started in 1956 as Little Southwestern League when Little Miami of the Warren County League joined with Bishop Fenwick and three Butler County League teams, who remained in the BCL initially. Little Miami returned to the WCL and was replaced by Lakota in 1959, prompting a rebrand to become the Southwestern Ohio Conference. While temporarily staving off defections to the Mid-Miami League by absorbing the rest of the BCL and having members concurrently in the MML and SOC, the conference was down to four members by 1970. After changing the name to the PVL in 1972, the league only lasted three years, as New Miami and Ross joined the Wayne Trace League, while Edgewood and Madison retained their membership in the MML.
