The papal conclave of 1492 (6–11 August 1492) was convened after the death of Pope Innocent VIII (25 July 1492). It was the first conclave to be held in the Sistine Chapel.

Cardinal Rodrigo Borja was elected unanimously on the 4th ballot as Pope Alexander VI. The election is notorious for allegations that Borja bought the votes of his electors, promising them lucrative appointments and other material gifts—a practice known as simony. Concerns about this conclave led Pope Julius II to create stronger rules against simony in 1503.
