Ulderico Carpegna (24 June 1595 – 24 January 1679) was an Italian jurist and Cardinal.

Through his episcopal consecration of Paluzzo Paluzzi Altieri degli Albertoni, he is part of the episcopal lineage of Pope Francis.

He is also connected to the lineage of Pope Benedict XVI.

Carpegna was a patron of Francesco Borromini and commissioned the Baroque architect important works of transformation and expansion of his palace at Fontana di Trevi.

As a token of gratitude, Borromini named the prelate executor of his will and bequeathed him money and objects of considerable value "for", as he wrote, "the infinite debt I have toward him".
