The 2012 Big Ten Conference Baseball Tournament was held at Huntington Park in Columbus, Ohio from May 23 through 26. The top six teams from the regular season participate in the double-elimination tournament to determine the league champion. Purdue won their first tournament championship and earned the Big Ten Conference's automatic bid to the 2012 NCAA Division I Baseball Tournament. This was also Purdue's second year ever winning a conference championship in baseball, having won the conference regular season in 1909.
