Thunderbird High School is a public high school located in northwestern Phoenix, Arizona. The school is a part of the Glendale Union High School District.

Some schools in the Washington Elementary School District feed into Thunderbird High School.

Feeder junior high schools include Mountain Sky Junior High School and Cholla Middle School.

The school opened in 1972. Greenway High School opened the following year; both schools feature the same architectural blueprints. Designed by Rossman Partners the buildings were constructed exclusively of metal with minimal ornamentation.^[2] Twin City Construction Company of Fargo, North Dakota built the school. The construction company was later fired by the district for failing to meet the construction deadline, this would later result in a lawsuit being filed by the company. Remaining construction work was completed by other contractors.^[3] Thunderbird had rotating walls and open concept classrooms when it opened. By 1976, the school had filled up with more than 2,100 students,^[4] in 1976 the first class to have gone through all four years (freshman-senior) at the school graduated, and by 1979, that number reached its peak, with 2,742 students attending Thunderbird. Over time, enrollment declined, however; by the mid-1980s, the school's size increased at just below 2,000 students and has since slowly decreased to its current size.
