The IT University of Copenhagen (Danish: IT-Universitetet i København), often abbreviated and referred to as ITU (also in Danish), is a public university and research institution in Copenhagen, the capital of Denmark. It is specialized in the multidisciplinary study of information technology.

The IT University of Copenhagen was established in 1999, which makes it Denmark's youngest university. At that time, it was—in Danish—called "IT-højskolen". In 2003, when a new Danish university law was passed, the IT University was officially appointed a university, and changed its name accordingly.

In 2004, the university moved to its own new building in Ørestad, a newly developed area in Copenhagen on the island of Amager. The new building was designed by Danish architect Henning Larsen. The university is located right between the University of Copenhagen's new South Campus and the headquarters of the Danish Broadcasting Corporation (DR), and close to the DR Byen metro station. In 2020, the university extended its campus, taking over facilities in the neighboring DR complex.

The university originally only accepted students with a Bachelor's degree to its offered Master programs, but started its first Bachelor of Science program in Software Development in August 2007. As of 2018, the IT University offers four Bachelor programs (two of which are internationally oriented and taught in English), five Master study programs (two of which are internationally oriented and are taught in English), professional Master's study programs, a Diploma program, and approximately 100 courses each semester.

The IT University takes a multidisciplinary approach to the study of information technology, drawing from a variety of academic perspectives. These include the natural sciences (traditional computer science), software engineering, data science, information economics, information systems, computational social science, science and technology studies (STS), CSCW, computer games studies, and the cultural and aesthetic aspects of IT.

There are approximately 90 faculty members, 50 Ph.D. students and more than 2,000 students. Among all admitted Bachelor and Master students at the IT University in 2019, 38 per cent were females
