Otago Girls' High School (OGHS) is a secondary school in Dunedin, Otago, New Zealand. It was opened 6 February 1871, after a long campaign by Learmonth Whyte Dalrymple. It is one of the oldest girls' state-run secondary schools in the Southern Hemisphere and has been described as the sixth oldest school of this type in the world.
The school has its own radio show on Otago Access Radio.
At its foundation the school occupied a neo-classical building on its present site which it shared with Otago Boys' High School. A new building on another site was built for the boys which they moved to in 1885. In 1910 the present main block was opened, designed by Edmund Anscombe (1874âÂÂ1948) and the old building on Tennyson Street was demolished. Temporary structures were replaced in the 1970s by Ministry of Education blocks, contextualised by the use of brick to the Anscombe building. In the 1980s the main block was scheduled for demolition. After protest it was restored and extended with an addition designed by Ted McCoy, and in 1987 was listed as a Category I Historic Place. The school has since acquired part of the old King Edward Technical School site. It has erected structures there accessible by way of a pedestrian underpass beneath Smith Street.
The school gained international attention in February 2022 after a Muslim student was beaten by her peers for wearing a hijab, which resulted in the student being hospitalised with a concussion. The incident led to an international and domestic outcry, with support for the student coming from Bella Hadid, Sonny Bill Williams, among others. Two of the students responsible for the attack were subsequently expelled while a third was referred to counselling. Principal Bridget Davidson confirmed that the school was working with the victims, Muslim community and Police to address the bullying and assault. Otago Muslim Association chairman Mohammad Rizwan welcomed the outcome.
