Pedro Álvarez de Toledo y Leiva, 1st Marquis of Mancera[1] (c. 1585–1654), was a Spanish nobleman, general, colonial administrator, and diplomat.

He served with the Spanish armies in Italy, rising to the rank of lieutenant general in the royal galleys of Sicily.

He traveled to the Viceroyalty of Peru with his son Antonio Sebastián de Toledo, who later became the Viceroy of New Spain (1664–73) and 2nd Marquis of Mancera.

As viceroy, Pedro de Toledo introduced the papel sellado (literally, sealed paper).

In these was introduced the mancerina, a ceramic or silver saucer with a framework for holding a jícara, or chocolate cup.
