Haberdashers' Girls' School is a private day school in Elstree, Hertfordshire. It is often referred to as "Habs" (or "Habs Girls" to distinguish it from the neighbouring Haberdashers' Boys' School). The school was founded in 1875 by the Worshipful Company of Haberdashers, one of the Great Twelve Livery Companies of the City of London.

In 1690, Robert Aske gave the Haberdashers' Company £20,000 to set up a hospital and home for 20 elderly men and a school for 20 boys at Hoxton, just north of the City of London. The school came decidedly second to the home for elderly men. There were no new boys between 1714 and 1739 because the foundation was short of funds. The hospital was rebuilt during 1824–26 and the foundation was reorganised in 1873 when four schools were established: two at Hoxton, and two at Hatcham, New Cross in south-east London. Boys and girls were taught separately at each site. All four schools opened in 1875, the Hoxton schools offered a basic English education and the Hatcham schools covered a wider syllabus. In 1891, Hatcham Girls moved to new premises half a mile away, designed by Henry Stock, while Hatcham boys took over the Girls’ buildings.

Early in the 20th century, new sites for the Hoxton schools were purchased in Cricklewood (always referred to as Hampstead) for the Boys and Acton for the Girls. Both these schools became Direct Grant in 1946 and then fully independent, day, fee-paying schools in 1976. The need for expansion saw the Boys’ School move again to Elstree, Hertfordshire in 1961, followed by the Girls in 1974.

The previous site of the Girls' School, in Acton, became the Japanese School in London.

In March 2021, The Spectator reported that the school's governing body would be undertaking a review of their founder, Robert Aske's, legacy, including his ties to slavery. In September 2021, various news reports confirmed that the Aske's name would be dropped from both the names of the Boys' and the Girls' schools, and that they would be henceforth called Haberdashers' Girls' School and Haberdashers' Boys' School. although the name Aske would be retained by their governing body.

97% of girls achieve grades A* to B at A Level, and over 99% achieve A* - B at GCSE.
