Infanta Isabel Luísa of Portugal (Lisbon, 6 January 1669 – Palhavã, 21 October 1690) was a Portuguese infanta and the sole daughter of Peter II of Portugal and his first wife and former sister-in-law Maria Francisca of Savoy. She was the presumptive heir to the throne of Portugal between 1668 and 1689, the year her half-brother John was born. As such, she was styled Princess of Beira.
It was planned that she would marry Victor Amadeus II of Savoy, a first cousin through her aunt Marie Jeanne, Duchess of Savoy, then regent for her son. The marriage was opposed by most of the Savoyard court as it meant that Victor Amadeus would live in Portugal and his mother would remain in power. But that plan was not implemented.
Other proposed candidates included Gian Gastone de' Medici (future Grand Duke of Tuscany), le Grand Dauphin son of Louis XIV, Charles II of Spain, the Duke of Parma as well as a Count Palatine of Neuburg. Nothing came of these plans. For this she was nicknamed Sempre-noiva, "Always-engaged".
