James Hargest College is a large school of 1,882 students (as of 2023),^[4] in Invercargill, New Zealand. The school caters for students from year 7–13.

The school is divided into two campuses, known as James Hargest Junior Campus (Year 7–8) and James Hargest Senior Campus (Year 9–13). The campuses are at opposite ends of Layard Street and are separated by about a 20-minute walk (1.5 km).

James Hargest College is named after Brigadier-General James Hargest.

James Hargest Junior Campus was formerly known as Rosedale Intermediate School until it became part of the former James Hargest High School to make James Hargest College as part of the Ministry of Education review of schools in 2004. Other intermediate schools in the city merged with the newly formed James Hargest Junior Campus, increasing the school's roll and stretching resources. Because of this, a new technology block has been built, and several new classrooms have been built since the merge. There are 21 homeroom classrooms. The subjects in the New Technology Block (known as the Atrium) include Science, Art, Woodwork (known as Hard Materials), Foods & Fabrics technology, and an ICT & Media Suite.

The Senior Campus covers Years 9–13, and as of 1 July 2020 had 1271 enrolled students.^[5] The school has a New Zealand $ 2.2 million library, which officially opened in 2004 that also includes the Guidance and Careers Centre, as well as a Library Reading Room and Library Classroom. The library's classroom has desks, computers and an interactive whiteboard, as well as the reading room where students can browse the library's collection of magazines, newspapers and many books. There are also DVD movies available for hire to students.
