Sixtus IV became ill on 8 August 1484; this illness worsened on 10 August while the pope was attending an event in Rome. He felt unwell that evening and was forced to cancel a meeting he was to hold with his cardinals the following morning. The Pope grew weaker during the night of 11 August and he was unable to sleep. Sixtus IV died the following evening – 12 August.<ref>{{cite web|url=http://www.csun.edu/~hcfll004/SV1484.html|title=Sede Vacante 1484|date=2 May 2015|access-date=22 January 2019}}</ref>

The envoy of the Medici family summed up Sixtus' reign in the announcement to his master, "Today at 5 o'clock His Holiness Sixtus IV departed this life – may God forgive him!"<ref>Perie, The Triple Crown, Spring 1935 p. 26</ref>

Pope Sixtus's tomb was destroyed in the [[Sack of Rome (1527)|Sack of Rome in 1527]]. Today, his remains, along with the remains of his nephew Pope Julius II (Giuliano della Rovere), are interred in St. Peter's Basilica, in the floor in front of the monument to Pope Clement&nbsp;X. A marble tombstone marks the site.

His bronze funerary monument, now in the basement Treasury of [[St. Peter's Basilica]], made like a giant casket of goldsmith's work, is by [[Antonio del Pollaiuolo]]; it was completed by 1493. The top of the casket is a lifelike depiction of the Pope lying in state. Around the sides are [[bas-relief]] panels depicting allegorical female figures representing Grammar, Rhetoric, Arithmetic, Geometry, Music, Painting, Astronomy, Philosophy, and Theology—the classical [[Liberal arts education|liberal arts]], with the addition of painting and theology. Each figure incorporates the oak tree ("rovere" in Italian), symbol of Sixtus IV. The overall program of the panels, their beauty, complex symbolism, classical references and their relative arrangement are compelling and comprehensive illustrations of the Renaissance worldview. None of them actually states how he died.
