Southgate School is a coeducational secondary school and sixth form located in the Oakwood area of London, England. The school is situated just east of the Cat Hill roundabout of the A111 and A110, between Cockfosters and Oakwood tube stations. The Trent Park campus of Middlesex University is nearby to the north, on the northern fringe of Greater London's conurbation. Middlesex University has its Cat Hill campus nearby to the east. Although once historically in Southgate, the school is now in the parish of St Thomas, Oakwood, on the boundary with Cockfosters to the west, and on the western edge of Enfield borough, 500 metres east of the Barnet boundary.
