The State Institute for Racial Biology (SIRB, Swedish: Statens institut för rasbiologi, SIFR) was a Swedish governmental research institute founded in 1922 with the stated purpose of studying eugenics and human genetics. It was the most prominent institution for the study of "racial science" in Sweden.^[1] It was located in Uppsala. In 1958, it was renamed to the State Institute for Human Genetics^[2] (Institutionen för medicinisk genetik) and is today incorporated as a department of Uppsala University.

The institute's first head was Herman Lundborg.^[3] He retired in 1935. He was succeeded by Gunnar Dahlberg.^[1] An early research priority was studying the commonness of the "Nordic" racial traits in the Swedish population and the alleged downsides of race-mixing between the majority population and Finns and the Sámi people.^[1][4] Between 1936 and 1960, the majority of research projects at SIRB concerned medical genetics but racial science was still an important aspect of the institute.^[1]
