Hoërskool Eldoraigne is a public Afrikaans medium co-educational high school situated in the suburb of Eldoraigne in Centurion in the Gauteng province of South Africa. It is one of the most academic schools in Gauteng and its learners are known as Eldo's.

Situated on the corner of Christopher street and Dordrecht street, Eldoraigne was founded in 1974 as an Afrikaans secondary school. The first principal was Mr G. Visagie, previously vice-principal at Hoërskool Menlopark.

Mr Frank Roos became the headmaster in 1996 and served in that position up to his retirement, 19 years later. Roos was formerly a teacher at HTS Witbank (1973-), department head at Hoërskool Ben Viljoen in Groblersdal, vice principal at Hoërskool Verwoerdburg (current Hoërskool Centurion), and senior vice principal at Hoërskool Gerhard Maritz. Mr Roos majored in Entomology as student, and Biology remained his favourite subject subsequently. He was a writer of text books for the Education Department, served on its biology research committee, and served as head examinator for the National Education Department. Mr Roos was succeeded in 2015 by Dr Anton Prinsloo.

At the time of his appointment Prinsloo expressed the hope that the school's brand could be improved from "fifth" to first place nationally, but his tenure was noted for heightened tensions and a very high turnover of staff. Prinsloo was previously a teacher at Hoërskool Vorentoe (87-88) and Hoërskool Helpmekaar (89-), before he served as vice principal at Hoërskool Riebeekrand and Hoërskool Noordheuwel (-98) respectively. By 1997 he had obtained his M.Ed. and D.Ed. from RAU, and was headmaster at Hoërskool Bastion from 1998 to 2014.

In April 2018 an Eldoraigne pupil paid Hoërskool Waterkloof a visit, intending to ask a Waterkloof girl to his prom dance. The visit however devolved into a scuffle between the boy and two of Waterkloof's staff members, and Prinsloo's office subsequently informed the media that the boy was "not enrolled at the school since the incident". In 2021 the Gauteng Education Department temporarily relieved Prinsloo of his duties at Eldoraigne, after fellow staff accused him of victimization and bullying, and some parents allegedly signed a petition to remove him. His deputy, Mr Dave du Plessis, was appointed as acting principal during his three months long absence.

When the department moved to charge Prinsloo with misconduct, his accusers however decided to "stand their ground" by refusing to testify in a disciplinary hearing. The department consequently dismissed their complaints, and reinstated Prinsloo in his former position. Prinsloo resumed his duties on August, 17th, and claimed that he was inundated with messages in support. A week later some 40 parents and pupils however gathered to hand over a petition to the South African Teachers' Union (SAOU) which was signed by hundreds of respondents. They expressed their concern and dissatisfaction with Prinsloo's return, and the impact they believed it would have on staff and pupils. The school's governing body indicated that it was reserving its options, before the department relented and once again recalled Prinsloo. Prinsloo was cleared of misconduct after a disciplinary hearing in 2022, but not immediately reinstated. His lawyer commented that the accusations were preposterous and devoid of truth.
