The 2011 National Schoolboy Cup was the 37th staging of Australia’s premier secondary schools competition.

The Southern Conference (ACT/NSW) featured the same 12 schools from 2010, split into three pools and playing each other once.

The top side in each pool was then joined by the Queensland champions, Palm Beach Currumbin State High, in the national semi finals.

On 2 September, Hills Sports High defeated Matraville Sports High in the final, winning their second consecutive Schoolboy Cup.
