Thorns Collegiate Academy is a coeducational secondary school located in Brierley Hill, West Midlands, England.

It serves the southern half of Brierley Hill around Withymoor Village and Quarry Bank.

The first buildings at the present site were opened in the early 1970s as an annexe to the Quarry Bank school for older pupils.

By 1975, almost 20 mobile classrooms had been erected at the new site in Stockwell Avenue as it now accommodated the majority of the school's pupils.

The English, ICT and Vocational Education block at the school was declared unsafe in September 2010 and the cost of making it safe was estimated at £600,000.
