The 2023 Schoolboy Cup, known as the NRL Schoolboy Cup, was the 49th staging of Australia’s premier secondary schools competition.

The Southern Conference’s Peter Mulholland Cup underwent a format change, with 20 teams competing over five pools – two Sydney/Canberra pools, a northern New South Wales pool, a Victorian pool and a seeded pool.

Westfields Sports High defeated Palm Beach Currumbin State High in the final, the second title in the school’s history.
