Aksel Sandemose (né Axel Nielsen; 19 March 1899 – 6 August 1965) was a Danish-Norwegian writer whose works frequently elucidate the theme that the repressions of society lead to violence.

After the Nazi German occupation of Norway during World War II, he fled to Sweden in 1941 due to his peripheral association with the Norwegian resistance movement.

His most notable work was En flyktning krysser sitt spor (1933).

The novel was translated into English and published under the title A Fugitive Crosses His Tracks in 1936 by Alfred A. Knopf.

In this satirical novel about Danish village life, Sandemose introduced the concept of the Law of Jante, a listing of ten cultural rules which describe a pattern of group behaviour towards individuals common to Nordic countries.
