Hans Aas (22 September 1880 – 5 August 1960) was a Norwegian trade unionist. Aas was born in Tromsø. He joined his first trade union in 1906, and chaired the union Norsk bokbinder- og kartonnasjearbeiderforbund from 1914 to 1930. Having broken away from the Labour Party and joined the Communist Party in 1923, Aas later worked as a manager in the newspaper Arbeidet. He was a member of the secretariat of the Norwegian Confederation of Trade Unions from 1920 to 1923, then a deputy who met regularly in the place of Ole O. Lian, then a secretariat member again from 1927 to 1929. He formed a Communist minority in the secretariat together with Elias Volan, but they were replaced in 1929.
