Harris City Academy Crystal Palace is a mixed-sex secondary school in Croydon, south London, England.

Sylvan, judged to be under-performing, re-opened as a City Technology College (CTC) sponsored by Lord Harris of Peckham.

The work on the new buildings was completed by November 2010, with a new sixth form block, reception, internal walkways and classrooms now in use.

The Sixth Form at Crystal Palace delivers primarily AS and A level courses and around 400 students are based there.

Opportunities for students have included visiting NASA astronaut training facilities in HACCP and Florida in the USA and many residential trips.

These students work together with teachers and leading educationalists in order to explore ways of further improving teaching and learning.

The sixth form teaches a variety of subjects, and is also part of a rugby training school in conjunction with Harlequins.

As of August 2023, the Harris Federation runs 52 primary and secondary academies in London and Essex.
