Stockholm University (Stockholms universitet) is a state university in Stockholm, Sweden. It has about 37,000 students studying at four faculties.

In 1878, the university college Stockholm högskola started its operations with a series of lectures on natural sciences, open to curious citizens (a tradition still upheld by yearly publicly open lectures). Notable in the university's early history is the appointment of Sofia Kovalevskaya to hold a chair in mathematics in 1881, making her the third female professor in Europe. In 1904 the college became an official degree granting institution.
