Anna Catherine Constance Vasa of Poland, Polish: Anna Katarzyna Konstancja Waza (7 August 1619 in Warsaw – 8 October 1651 in Cologne) was a Polish princess, daughter of King Sigismund III Vasa and his second spouse Constance of Austria.
In 1632 the parliament bestowed her with the counties Brodnickie, Gołubskie and Tucholskie. In 1637, a marriage was suggested between Anne Catherine Constance and Ferdinand Charles, Archduke of Austria, heir of Tyrol and nephew of Ferdinand II, Holy Roman Emperor. Despite arrangements in 1639 and 1642, the marriage never actually took place, because of the age of Charles Ferdinand and because of disagreement about the amount of dowry. On 8 June 1642 she married Philip William, Elector Palatine. She died without issue. She was buried in the church of the Jesuits in Düsseldorf.
