Pre-NCAA intercollegiate championships

The National Collegiate Athletic Association (NCAA), founded in 1906, is the major governing body for intercollegiate athletics in the United States and currently conducts national championships in its sponsored sports, except for the top level of football. Before the NCAA offered a championship for any particular sport, intercollegiate national championships in that sport were determined independently. Although the NCAA sometimes lists these historic championships in its official records, it has not awarded retroactive championship titles.

Prior to NCAA inception of a sport, intercollegiate championships were conducted and usually espoused in advance as competitions for the national championship. Many winners were recognized in contemporary newspapers and other publications as the "national intercollegiate" champions. These are not to be confused with the champions of early 20th-century single-sport alliances of northeastern U.S. colleges that were named "Intercollegiate League" or "Intercollegiate Association." These leagues generally included some of the colleges that later became the Ivy League, as well as an assortment of other northeastern universities.

Even after the NCAA began organizing national championships, some non-NCAA organizations conducted their own national championship tournaments, usually as a supplement to the NCAA events. A notable example is that of NCAA Division III men's volleyball. Although the NCAA Men's National Collegiate Volleyball Championship, established in 1970, was in theory open to D-III schools, none had received a berth in that tournament. As a result, a separate championship event, open only to D-III schools, was created in 1997. That event was discontinued after its 2011 edition once the NCAA announced it would sponsor an official Division III championship starting in 2012.

The historical championship event outcomes included in the Section 1 list were decided by actual games organized for the purpose of determining a champion on the field of play. Lists of other championships for collegiate athletic organizations are referenced in Sections 2.1 through 2.6 of this list. (See Table of Contents)
