Torsten Karl Viktor Nothin (13 February 1884 – 1 March 1972) was a Swedish official and social democratic politician.

[1] Nothin was a member of the Första kammaren from 1921 to 1928, and served as Minister for Justice from 18 October 1924 to 7 June 1926.

[4] Nothin was chairman of about 20 committees and expert investigations,[4] including the Committee on the Hovrätterna (Kommittén angående hovrätterna) in 1926, Dalautredningen from 1930 to 1932, Statens organisationsnämnd ("National Organization Board") until 1932, Aviation Investigation of 1934 (1934 års luftfartsutredning), the "Mother Investigation" of 1935 (1935 års "mammututredning") and the Municipal Tax Preparation of 1936 (1936 års kommunalskatteberedning), and various negotiating delegations between the Crown and the City of Stockholm.
