Dag Terje Andersen (born 27 May 1957 in Frogn, Akershus) is a Norwegian politician for the Norwegian Labour Party.

In addition to professional politics he has worked at a steel mill and as a lumberjack, something that has given him a reputation for politically representing the average citizen.

In 1996 he became Minister of Agriculture, remaining in that post for slightly less than a year.

Andersen later became Minister of Trade and Industry on 29 September 2006, when Odd Eriksen resigned.
