NCAA Division III independent schools are four-year institutions that compete in college athletics at the National Collegiate Athletic Association (NCAA) Division III level, but do not belong to an established intercollegiate athletic conference for a particular sport. These schools may however still compete as members of an athletic conference in other sports. A school may also be fully independent, and not belong to any athletic conference for any sport at all. The reason for independent status varies among institutions, but it is frequently because the school's primary athletic conference does not sponsor a particular sport.
