The Eastern Intercollegiate Baseball League was a baseball-only conference that existed from 1930 to 1992. It consisted of the eight Ivy League schools along with Army and Navy. The league disbanded after the 1992 season, when Army and Navy joined the Patriot League and the Ivy League began sponsoring baseball.
