St Ignatius College is a Catholic voluntary aided secondary school for boys aged 11–18 in Enfield, London, England, founded by the Society of Jesus in 1894 and completely moved to its present site by 1987.

In 1907 the college was recognised by the Board of Education and began to receive public money towards its support.

In 1998 the school started to build the Octagon which houses a computer suite, chapel and a library.

[7] Michael Blundell became the college's first lay Headmaster when he succeeded Fr Antony Forrester SJ, in 1986.

Andrew Dickson took over the post on an interim basis until a replacement for John-Paul Morrison could be found.

Kelly took over from Dickson in 2014 and retired from his role in 2016 and was succeeded by Mrs O'Keeffe, the first female headteacher of a Jesuit secondary school in the United Kingdom.

[9] In 2023, the school was one of those identified as having buildings that could be structurally unsound because reinforced autoclaved aerated concrete had been used in their construction.

[12] The school motto Ad maiorem Dei gloriam – meaning "For the greater glory of God" – was abbreviated to AMDG and is still customarily appended to students' essays or homework.

A retreat is a time when, away from their usual environments of home and school, the pupils can reflect on their lives and on their relationships with others and with God.

Sports played at the college include: Football, Rugby union, Basketball, Tennis, Cross country running, Cricket, Swimming, and Cycling.

They provide spiritual, social, recreational, and sporting facilities so that they may serve the interests of not only the Old Ignatians but also of current pupils.
