Nelson College is the oldest state secondary school in New Zealand, a feat achieved in part thanks to its original inception as a private school. It is an all-boys school in the City of Nelson that teaches from years 9 to 13. In addition, it runs a private preparatory school for year 7 and 8 boys. The school also has places for boarders, who live in two boarding houses adjacent to the main school buildings on the same campus.

Nelson is a New Zealand city on the eastern shores of Tasman Bay at the top of the South Island. It is the oldest city in the South Island and the second-oldest settled city in New Zealand; it was established in 1841 and became a city by royal charter in 1858.
