The Nebraska School Activities Association (NSAA) is an organization that brings together public and non-public high schools in Nebraska. It is dedicated to promoting high ideals of citizenship, fair competition, sportsmanship, and teamwork among its member schools. The NSAA formulates and implements policies that complement the schools' curriculum programs, fostering uniformity in interscholastic activity competition.

Covering a wide range of sports and activities, the NSAA offers a diverse program for students. From fall sports like cross country, football, softball, and golf, to winter sports such as basketball, bowling, swimming, and wrestling, and spring sports including baseball, soccer, tennis, and track & field – there's something for everyone. Beyond athletics, the NSAA also supports activities like debate, journalism, music, play production, and speech.

The association provides resources, organizes events, and offers support to schools, coaches, officials, and judges. Founded on the principles of integrity and inclusivity, the NSAA promotes the health and physical welfare of all participants. By fostering an environment of fair play and teamwork, NSAA activities serve as a valuable complement to the academic education provided by member schools
