Karolinska Institutet (often translated from Swedish into English as the Karolinska Institute, the -et being a definite article, and in older texts often as the Royal Caroline Institute) is a medical university in Solna within the Stockholm urban area, Sweden, and one of Europe's largest and most prestigious medical universities. It was founded in 1810 on Kungsholmen on the west side of Stockholm; the main campus was relocated decades later to Solna, just outside Stockholm. A second campus was established more recently in Flemingsberg, Huddinge, south of Stockholm.
Karolinska Institutet is Sweden's third oldest medical school, after Uppsala University (founded in 1477) and Lund University (founded in 1666). According to the 2012 Times Higher Education World University Rankings, Karolinska Institutet is ranked 32nd worldwide, 6th in Europe, and 1st in the Nordic region  and according to the 2011 Academic Ranking of World Universities, Karolinska Institute is ranked 9th in the world in the field of clinical medicine and pharmacology and among the first 20 universities in life sciences.
The Karolinska University Hospital, located in Solna and Huddinge, is associated with the university as a research and teaching hospital. Together they form an academic health science centre. It is one of Sweden's largest centres for training and research, accounting for 30 percent of the medical training and 40 percent of the medical academic research conducted nationwide. While most of the medical programs are taught in Swedish, the bulk of the Ph.D. projects are conducted in English.
Karolinska Institutet was founded in the period between 1810 and 1811, following the Finnish War, as a training center for army surgeons.
The original name was at first 'Medico-Chirurgiska Institutet'. In 1817 the prefix Karolinska was added as a reference to the then-Swedish king Karl XIII (Carolus in Latin). The full name thus became Kongliga Carolinska Medico Chirurgiska Institutet. In 1968 this name was abbreviated to 'Karolinska Institutet'.
