Marlwood School (founded 1606) is a comprehensive state secondary school located in Alveston, South Gloucestershire, just north of Bristol, England. It is situated on the B3561 on the outskirts of the south-west of the village.
The school was founded in 1606 as Thornbury Grammar School. In the following centuries it was housed in a number of buildings throughout Thornbury, before finally moving to the buildings that are now the sixth form centre for The Castle School.
Thornbury Grammar School was relocated to new buildings on the outskirts of neighbouring Alveston in 1972 where it received its first comprehensive intake and was renamed Marlwood School under the headship of Terry Fazey.
It is a Beacon school and has attained the status of Science College, due to excellence at science. Marlwood has around 1,200 pupils and a sixth form department, with over 200 students studying AS, A2 and BTEC qualifications.
The school produces a newsletter known as 'Grapevine' as well as a once-a-term newsletter.
