St Nicholas' School is a private day school for girls in Church Crookham, a village at the southern edge of Fleet, Hampshire, England.

St Nicholas' School was founded in 1935 and moved to its present 30-acre site in 1996.

As the school grew, the original Victorian house has been extended, adapted and additional accommodation built.

The school became a charitable trust in 1966.

The school maintains the Christian ethos of its foundation, whilst welcoming pupils of all faiths and of none.
