Anja Rubik (born Anna Rubik; 12 June 1983) is a Polish model.
Rubik was born in Rzeszów, Poland. In 1988 she and her family moved to Greece. They later moved to Canada and to Umtata, South Africa. Among the schools she attended was one in Częstochowa, Poland. Rubik was introduced to modeling while attending a British high school in Paris. She wanted to finish her schooling before officially becoming a model, and so only worked on school holidays. Her mother, father and sister still reside in Poland.
