Ana Carolina Ardohain Dos Santos (born January 17, 1981 in Santa Rosa, Argentina), is a model and TV star in her home country. She is also known by the nickname "Pampita".

Her still photography work includes the likes of Victoria's Secret and Wonderbra. Ardohain also has hosted her own TV variety shows, "El Rayo" and "El Sitio", which were ratings winners.

During the 2002 World Cup campaign, Ardohain was voted to be the national football (soccer) team's representative, or "Godmother" as many called the honorary post.

Ardohain married model Martín Barrantes in November 2002. In September 2005 she separated from Barrantes in the midst of a tumultuous media-hyped rumor that she was having an affair (which she denied). She rather quickly began dating and living with Benjamín Vicuña, a famous actor from Chile. Santiago newspapers have published photos of Pampita walking her beagle, clearly showing that the model is pregnant (expecting a boy around April 2006).

Ardohain has generated some jealous comments from other Argentine models. Gossip columns frequently cited how models Nicole Neumann and Julieta Prandi called Pampita a "mucamita" (servant girl or maid) and "muqui" (short for mucamita), essentially labeling her as coming from short peasant stock and not worthy of the high-class world of fashion modeling.
