The International Physics Olympiad (IPhO) is an annual physics competition for high school students. It is one of the international Science Olympiads. The first IPhO was held in Warsaw, Poland in 1967.

Each national delegation is made up of five student competitors plus two leaders, selected on a national level. Observers may also accompany a national team. The students compete as individuals, and must sit for intensive theoretical and laboratory examinations. For their efforts the students can be awarded gold, silver, or bronze medals or an honorable mention.
