Andrea Patricia Clausen (born 1971) is a British-born Falkland Islands politician who served as a Member of the Legislative Assembly for the Stanley constituency from 2005 until 2009. Clausen was elected as a Member of the Legislative Council, which was reconstituted into the Legislative Assembly with the implementation of the 2009 Constitution.

She then went on to study Marine Biology at Bangor University where she gained a PhD in the subject. Clausen then moved back to the Falklands to work as a Scientific Officer for Falklands Conservation.[1]
