The Big Eight Conference sponsored championships in 21 sports (11 men's and 10 women's) at various times during its existence from 1907 to 1996.

[1] The conference began sponsoring women's sports in the mid-1970s under the direction of Assistant Commissioner Steven J. Hatchell.

Due to its common history with the Missouri Valley Conference, Big Eight championships from the 1907–08 through the 1927–28 academic year are also claimed by the MVC.

From the 1946-47 through the 1978-79 season, the Big Eight hosted a mid-season holiday tournament in which all of the league teams participated.

From the 1946-47 through the 1957-58 season when the conference had fewer than eight members, non-member schools would be invited in order to field an 8-team tournament.

All Big Eight men's basketball post-season tournaments were held at Kemper Arena in Kansas City, MO.

However, from the 1976-77 to 1984-85 season, quarterfinal rounds were played on the home courts of the top four seeds in the tournament.

‡ Oklahoma initially won the 1972 title, but after it was found that they used ineligible players, they were penalized by the NCAA, though they did not force OU to forfeit games.

†Oklahoma State did not accept the trophy in 1992 in order to lessen any consequences stemming from an NCAA investigation of improper payments made to its student athletes.
