Nicholas Breakspear Catholic School (NBS) is a secondary school with academy status situated on the rural fringe of St Albans, an old Roman city in Hertfordshire, England.

The school takes its name from the 12th-century priest St Albans-born and educated Nicholas Breakspear, who, as Pope Adrian IV, is the only Englishman ever to have occupied the papal chair. The school makes an annual pilgrimage to his tomb in Rome. (The school goes to Rome each year, but has only once gone to the tomb)

After a 2008 renovation of the science classrooms, Chris Reeves made a nativity scene composed of sculptures made from the discarded 1960s desks.

In September 2013 the school celebrated its golden anniversary with a service offered by the Catholic Archbishop of Westminster at SS Alban and Stephen Church in the presence of the mayor of St Albans. The mass was followed by a tree-planting ceremony on the school grounds.

It was categorized in 2016 as a 'Good' school but remained a school with below average teachers.

On 13 January 2016, Prince William ate lunch with Breakspear students at John Henry Newman School as he waited for paramedics. The East Anglian Air Ambulance, of which the Duke of Cambridge is part of, frequently uses the Newman School fields.

The student leaders' take part in a trip to Hoima and Kasambya in Uganda supporting a charity; Kiddies Support Scheme (KiSS) helping families become self-sufficient. To date this team has led a school community to raise over £50000 for this charity.

As of a November 2023 Inspection the school was rated 'Outstanding'.
