St John's College was a private day and boarding school located in Southsea, Hampshire, England. It was founded by the De La Salle brothers in 1908. In May 2022, the Governors announced that the school would not re-open for the academic year starting that September, citing declining student numbers, under-investment and the impact of the COVID-19 pandemic as the causes. In August 2022, St John's College appointed administrators and went into liquidation. The head of the college at the time of closure was Mary Maguire.

The college has several notable alumni, known as Old Johannians, including the Lord Chief Justice of England and Wales Lord Burnett of Maldon, England footballer Alex Oxlade-Chamberlain and BBC newsreader George Alagiah.
