Rasmus Johan Michael Hansson (born 4 September 1954) is a Norwegian biologist, civil servant, environmental activist and a former national spokesperson for the Green Party.

He and a fellow student (Jørn Thomassen) were convicted of sitting down on a road meant for "construction traffic".

[6][7] In 2014 Aftenposten said that "The fines, in the order of [Norwegian] kroner ten thousand were too high for the students so they both chose the option of having themselves imprisoned for a few weeks.

[16] Hansson argues that consumption in Norway needs to be reduced in order to cope with the environmental challenges.
