Ipswich School is a public school (English private boarding and day school) for pupils aged 3 to 18 in Ipswich, Suffolk, England.
North of the town centre, Ipswich School has four parts on three adjacent sites. The Pre-Prep and Nursery were established in 1883 with the aim of preparing children aged 7 to 11 for entry into the Senior School. The Senior School occupies the main school site. The main buildings are a distinctive example of Victorian architecture, with Tudor style brick. The main building and chapel are both Grade II listed. The school buildings surround a central playing field and cricket square along with the Cricket Pavilion. The remainder of the School's sport's fields are located at a nearby site on the edge of the town. The School has a new purpose-built music school, adjacent to the Cricket Pavilion.
Within the Senior School the students are divided into three: the Lower School (Years 7 and 8), the Middle School (Years 9-11) and the Sixth Form (Years 12 and 13).
The School operates on an independent, fee-charging basis, with a few scholarships including sports, academic and art and music and means-tested bursaries. It selects pupils by the use of entrance exams.
The School was designated as having a Church of England Religious Character. The school has, however, not chosen to register as having a Religious Charter under the 2009 order.
