Olimpia Maidalchini Pamphilj, Princess of San Martino (26 May 1591 – 27 September 1657), (also spelled Pamphili and known as Olimpia Pamphili), was the sister-in-law of Pope Innocent X (Pamphili). She was perceived by her contemporaries as having influence regarding papal appointments.

She is not to be confused with her daughter-in-law Olimpia Aldobrandini, who married her son Camillo.
