Johann Burchard, also spelled Johannes Burchart or Burkhart (c.1450–1506) was an Alsatian-born priest and chronicler during the Italian Renaissance.
He was born at Niederhaslach, now Bas-Rhin, Alsace, France. Of humble origins, he was educated by the collegial chapter of St. Florent in Niederhaslach and eventually became secretary to the vicar general of the Bishop of Strasbourg. Suspected of theft, he left his position with the vicar and went to Rome about 1467. Burchard was ordained a priest in 1476.
He became a Protonotary Apostolic in February 1481, and was appointed Master of Ceremonies to Pope Sixtus IV in 1483, having bought the office for 450 ducats. He held it until his death on 16 May 1506, successively acting as Ceremoniere to Innocent VIII (1484–1492), Alexander VI (1492–1503), Pius III (1503) and during the early years of Julius II.
In Rome, Burchard joined the Confraternity of Santa Maria dell'Anima and quickly rose to become its provost. It was while he held this office that the decision was taken to rebuild the church of Santa Maria dell'Anima for the Jubilee of 1500. The church was built in the style of a Hallenkirche that was typical for Northern Europe. Andrea Sansovino was retained as architect by the confraternity. The facade was completed by Giuliano da Sangallo.
