North Allegheny Intermediate High School (NAI) is a suburban high school in the North Allegheny School District located in McCandless, Pennsylvania, a community north of Pittsburgh, Pennsylvania. It is one of two high schools in the district and serves grades 9 and 10. According to the National Center for Education Statistics, in 2011, the North Allegheny Intermediate High School reported an enrollment of 1,298 pupils in grades 9th and 10th. The school employed 93 teachers, yielding a student-teacher ratio of 13:1.

In 2007, the ethnic breakdown among the school population was 91.4% Caucasian, 6.3% Asian/Pacific Islander, 1.5% African American, and 0.7% Hispanic.

The school opened in 1954 as the North Allegheny Junior-Senior High School with 33 classrooms for grades 7-12. The design of the building was award-winning in its time, with distinct features include six letter-coded sloping hallways (or ramps) and most classrooms divided by outdoor courtyard spaces (unusual in school design for the time period). The building was expanded further in 1957 and 1963, adding classrooms in the rear of the building. The building became North Allegheny Senior High School (NASH) for grades 11-12 in 1969 upon the opening of Thomas E. Carson Intermediate High School (now Carson Middle School). The building assumed its current role as the Intermediate High School for grades 9-10 in 1974, when the new and current Senior High School in Wexford opened. A major renovation in 1997 expanded the building through the addition of the lower gym, larger cafeteria, and new front wing addition. The most recent renovation to the facility was completed in 2017.
