The Sistine Chapel ceiling (), painted in fresco by Michelangelo between 1508 and 1512, is a cornerstone work of High Renaissance art.

The Sistine Chapel is the large papal chapel built within the Vatican between 1477 and 1480 by Pope Sixtus IV, for whom the chapel is named. The ceiling was painted at the commission of Pope Julius II.

The ceiling's various painted elements form part of a larger scheme of decoration within the chapel. Prior to Michelangelo's contribution, the walls were painted by several leading artists of the late 15th century including Sandro Botticelli, Domenico Ghirlandaio, and Pietro Perugino. After the ceiling was painted, Raphael created a set of large tapestries (1515–1516) to cover the lower portion of the wall. Michelangelo returned to the chapel to create The Last Judgment, a large wall fresco situated behind the altar. The chapel's decoration illustrates much of the doctrine of the Catholic Church, serving as the setting for papal conclaves and many other important services.

Central to the ceiling decoration are nine scenes from the Book of Genesis, including The Creation of Adam. The complex design includes several sets of figures, some clothed and some nude, allowing Michelangelo to demonstrate his skill in depicting the human figure in a variety of poses. The ceiling was immediately well-received and imitated by other artists, continuing to the present. It has been restored several times, most recently from 1980 to 1994.

Context and creation

The walls of the Sistine Chapel had been decorated 20 years before Michelangelo's work on the ceiling. Following this, Raphael designed a set of tapestries (1515–1516) to cover the lowest of three levels; the surviving tapestries are still hung on special occasions. The middle level contains a complex scheme of frescoes illustrating the Life of Christ on the right side and the Life of Moses on the left side. It was carried out by some of the most renowned Renaissance painters: Sandro Botticelli, Domenico Ghirlandaio, Pietro Perugino, Pinturicchio, Luca Signorelli, and Cosimo Rosselli. The upper level of the walls contains the windows, between which are painted pairs of illusionistic niches with representations of the first 32 popes.

The original ceiling painting was by Pier Matteo d'Amelia, and had depicted stars over a blue background like the ceiling of the Arena Chapel decorated by Giotto at Padua. For six months in 1504, a diagonal crack in the chapel's vault had made the chapel unusable, and Pope Julius II (Giuliano della Rovere) had the damaged painting removed by Piero Roselli, a friend of Michelangelo.

Julius II was a "warrior pope" who in his papacy undertook an aggressive campaign for political control to unite and empower Italy under the leadership of the Catholic Church. He invested in symbolism to display his temporal power, such as his procession, in which he (in the Classical manner) rode a chariot through a triumphal arch after one of his many military victories. Julius II's project to rebuild St. Peter's Basilica would distinguish it as the most potent symbol of the source of papal power; he ultimately demolished and replaced the original basilica with a grander one intended to house his own tomb. The pope summoned Michelangelo to Rome in early 1505 and commissioned him to design his tomb, forcing the artist to leave Florence with his planned Battle of Cascina painting unfinished. By this time, Michelangelo was established as an artist;
