The 1389 papal conclave (25 October – 2 November) was convoked after the death of Pope Urban VI.

The conclave is historically unique because all of the cardinal electors were the creation of a single pontiff: Urban VI, the very pope who was being replaced.

None of the surviving cardinals created by previous popes recognized Urban VI as legitimate (see: Western Schism).

In addition, Urban VI had deposed four of his creatures, and three were absent, leaving only sixteen cardinal electors.
