Nashua High School North is a public high school located in Nashua, New Hampshire. The school's current location was erected in 2002 with its first class graduating in June 2005, one year after the city's high schools officially split into two locations and establishments (with the earlier high school now being renamed Nashua High School South). Generally, students living north of the Nashua River attend "North", as it is commonly referred to. However, students from either school can take certain classes at the other school and be bused over. The school's mascot is the Titans.
Nashua High School (as the south campus was referred to prior to the split in 2004) has been located at three different locations throughout the city, originally at a location at Spring Street, followed by the building that is now Elm Street Middle School, before finally coming to the current location on Riverside Drive.
Prior to the 2002–2003 school year, the Nashua school district followed a less standard placement system, which had the high school comprising grades 10 (sophomore) through 12 (senior), with grade 9 (freshman) being placed in with the city's three junior high schools (now following the middle school system/curriculum).
During the 2002–2003 and 2003–2004 school years, juniors and seniors attended classes at the newly constructed Nashua High School North campus, while sophomores attended school at the South location while it was being renovated. Until the 2004–2005 school year, freshmen still attended class at their respective junior high schools, but received credit and report cards from Nashua High.
The demographic breakdown by race/ethnicity of the 1,701 students enrolled for the 2018–2019 school year was:
