USA Astronomy and Astrophysics Olympiad (USAAAO) is a national-level selection stage in the United States used to identify top high school students for the International Olympiad on Astronomy and Astrophysics (IOAA) team.

Program Structure, Fields, and Selection
- A national screening system for U.S. high school students
- Typically involves multiple rounds of theoretical and conceptual exams
- Topics include basic astrophysics, celestial mechanics, optics, and observational data analysis
- Serves as a gateway to advanced training camps and the final U.S. IOAA team selection process
- Emphasizes combined knowledge of physics, mathematics, and astronomy problem-solving

Academic Value
Represents an early stage in the U.S. astronomy olympiad pathway and is part of the elite selection system for astrophysics-oriented students.

Impact on College Applications
Strong STEM credential, especially for physics and astronomy-related fields. Advancement to training camps or national team level significantly increases competitiveness for Top 20 and Ivy League admissions.
