Nikan High School (fa|مدرسهٔ نیکان) is a boys-only school located in the north of Tehran, Iran. Nikan is an ancient Persian-Zoroastrian name meaning "all the goodness in the world".
The school is associated with Alavi High School. Each class has a designated number called "doreh" which shows the number of years from the foundation of the school after which the class entered the first grade (primary school).
About 80% of the 8th grade class continues to 12th grade. The admission process consists of an entrance exam and an interview with the candidate and his parents.
The campus is located in the Elahiyeh neighborhood of Tehran.
