Tun Hussein Onn University of Malaysia (Malay: Universiti Tun Hussein Onn Malaysia; abbreviated as UTHM) is a public university in Batu Pahat, Johor, Malaysia. It was formerly known as the Tun Hussein Onn Institute of Technology (Malay: Institut Teknologi Tun Hussein Onn (ITTHO)) and the Tun Hussein Onn University College of Technology (Malay: Kolej Universiti Teknologi Tun Hussein Onn (KUiTTHO)). Along with other public university colleges, KUiTTHO was promoted to full university status since year 2007. The name UTHM was officially launched by the then education minister, Dato' Seri Hishammuddin Bin Tun Hussein.

The establishment history of Universiti Tun Hussein Onn Malaysia started off on 16 September 1993. The university was formerly known as Pusat Latihan Staf Politeknik (PLSP). The core business of PLSP then was to train and produce polytechnics academic staff in various engineering fields. The training institute was jointly administered by Universiti Teknologi Malaysia and the Ministry of Education Malaysia.

Three years later, PLSP was upgraded to Institut Teknologi Tun Hussein Onn (ITTHO). This promotion is an acknowledgment to the institution that has excelled in producing human resources for technical education.

On 27 September 2000, the institute achieved another milestone when the Malaysian government agreed to award a university-college status to the institute. This was to recognise its contributions in science and technology-based development as well as in helping the nation to achieve its aspiration. With the new status, the institution was known as Kolej Universiti Teknologi Tun Hussein Onn (KUiTTHO) and the official announcement was made by Tan Sri Dato’ Seri Musa bin Mohamed, the then Minister of Education.

The Malaysian government, on 20 September 2006, agreed to award the university-college a full university status and changed its name to Universiti Tun Hussein Onn Malaysia. On 1 February 2007, Datuk Mustapha Mohamed, the Minister of Higher Education officially announced the change of status. Subsequently, Dato’ Seri Hishamuddin Tun Hussein Onn then made the official declaration of the change of name on 2 March 2007.
