Minchenden School was a mixed secondary school situated in Southgate, North London, established in 1919 with 90 pupils. It merged with Arnos School in 1984.

The school was established in 1919 in Tottenhall Road as a mixed secondary school. In 1924, it moved to Southgate House, where it remained until 1987. The staff and pupils built an observatory. From 1960 to the early 1970s, there was an annexe in the Fox Lane school, Palmers Green. The annexe catered for the 1st 2 years of pupils. The school's English department was particularly strong. Head of English Douglas Barnes 1959-1966 introduced a series of important innovations in teaching methods. In 1967, Minchenden Grammar School was converted from a grammar school to Minchenden School, a comprehensive school, with the upper school in High Street and the lower school in Fox Lane. It was merged with Arnos School in 1984 to form Broomfield School, after the Conservative council sold the extensive playing fields to a development company to build homes, with the original Southgate House protected as a Grade I listed building.

The building is now used by Durants School, having previously been used by Southgate College.
