List of NCAA conferences
The National Collegiate Athletic Association (NCAA) is divided into three divisions based on scholarship allocation. Each division is made up of several conferences for regional league competition. Unless otherwise noted, changes in conference affiliation will occur on July 1 of the given year.
Under NCAA regulations, all Division I conferences defined as "multisport conferences" must meet the following criteria:
- A total of at least seven active Division I members.
- Separate from the above, at least seven active Division I members that sponsor both men's and women's basketball.
- Sponsorship of at least 12 NCAA Division I sports.
- Minimum of six men's sports, with the following additional restrictions:
- Men's basketball is a mandatory sport, and at least seven members must sponsor that sport.
- Non-football conferences must sponsor at least two men's team sports other than basketball.
- At least six members must sponsor five men's sports other than basketball, including either football or two other team sports.
- Minimum of six women's sports, with the following additional restrictions:
- Women's basketball is a mandatory sport, with at least seven members sponsoring that sport.
- At least two other women's team sports must be sponsored.
- At least six members must sponsor five women's sports other than basketball, including either football or two other team sports. If a conference officially sponsors an NCAA "emerging sport" for women (as of 2020, acrobatics & tumbling, equestrianism, rugby union, triathlon, or wrestling), that sport will be counted if five members (instead of six) sponsor it.
Football Bowl Subdivision
Conferences in the Football Bowl Subdivision must meet a more stringent set of NCAA requirements than other conferences. Among these additional NCAA regulations, institutions in the Football Bowl Subdivision must be "multisport conferences" and participate in conference play in at least six men's and eight women's sports, including football, men's and women's basketball, and at least two other women's team sports. Each school may count one men's and one women's sport not sponsored by its primary conference toward the above limits, as long as that sport competes in another Division I conference. The men's and women's sports so counted need not be the same sport.
Schools in all divisions that sponsor athletic programs for only one sex/gender need only meet the sports sponsorship requirements for that sex/gender.

- While the Ivy League considers its athletic conference to have been established in 1954, the history of the athletic league can be traced back decades earlier:
- In 1901, the Eastern Intercollegiate Basketball League (EIBL) was formed by five schools that would later become part of the current Ivy League; the EIBL membership eventually became identical to that of the future all-sports league. The EIBL was directly absorbed into the all-sports Ivy League, which considers the EIBL to be part of its history.
- In 1945, the Ivy Group Agreement, which governed competition and policies among the Ivy schools in football, was signed by all eight schools that eventually formed the all-sports league.
- The official formation of the athletic Ivy League came in 1954, when the Ivy Group Agreement was extended to cover all sports.
- The Ivy League, by NCAA count, sponsors 28 NCAA-sanctioned sports. The Ivy League awards separate men's and women's fencing championships, while the NCAA considers fencing a single coeducational sport. Additionally, the Ivy League sponsors championships in the non-NCAA sports of men's rowing plus men's and women's squash.

Unlike the other two divisions, Division III institutions cannot offer athletic scholarships. Among the other NCAA Division III requirements, schools have sports sponsorship requirements set by the NCAA. All institutions, regardless of enrollment, must sponsor at least three team sports for each sex/gender, and each playing season represented by each sex/gender.
A sports sponsorship rule unique to Division III is that the total number of sports that must be sponsored differs by a school's full-time undergraduate enrollment. Schools with an enrollment of 1,000 or fewer must sponsor at least five sports for men and five for women; those with larger enrollments must sponsor six men's and six women's sports. As in the other divisions, teams that include both men and women are treated as men's sports for the purpose of these regulations.

Four of the seven final ALC members are full Big Ten members. Johns Hopkins went independent before joining Big Ten women's lacrosse in the 2017 season.

Two members joined the new National Collegiate Hockey Conference, one member joined Hockey East, and the remaining five members joined or rejoined the Western Collegiate Hockey Association.
