All Saints Catholic High School is a Knowsley based Roman Catholic secondary school educating pupils aged 11–18 years of age in the Kirkby area of Merseyside, England. The school also operates a sixth form.

All Saints CCfL opened on 11 January 2010, following the closure of the Bewley Drive site in December 2009. The Bewley Drive site closed because of Knowsley's Building schools for the future scheme. All Saints followed the other 10 Knowsley schools in creating 7 new "centres for learning".

St Gregory's School on Bewley Drive in Southdene, Kirkby merged with St Kevin's School Northwood to form All Saints Catholic High School. St Gregory's School was the first girls' catholic comprehensive school in England, in Southdene. St Kevin's RC School had over 2000 boys, and was the largest comprehensive school in England.
