St Paul's Catholic School is a comprehensive co-educational secondary school in Leadenhall, Milton Keynes, England. It has specialist science and language college status and is also a Teacher Training College.

The school was inspected again in 2005 and 2008, and in both cases it was judged to be "outstanding".

The school was inspected in late 2013, and was judged as "requires improvement" in every category. The report was quoted as saying: "It is not good because; Students do not make consistently good progress throughout the school, particularly the more able. There is also variation in standards between subjects at GCSE level. Not all teachers have sufficiently high expectations and do not plan lessons which challenge students according to their assessed needs, particularly those that are more able." In a further inspection in March 2016 the school was rated as "good".
