Giovan Francesco Buonamici (1692- 4 August 1759) was an Italian architect and painter of the Baroque period, active mainly around Ravenna, Fano, and his native Rimini.
Only one independent painting (1723) by Buonamici is known, depicting the Consecration of Monsignor Maffeo Nicolò Farsetti.
He began working as an architect for the Cathedral of Ravenna under the patronage of the archbishop Farsetti.
In 1731–1732, he worked on the restoration of the cappella Sancta Sanctorum in Basilica of San Vitale, Ravenna.
He was particularly active in his native Rimini, where he worked in the local Pescheria (1747); the renovation of the church of Santi Giovanni e Paolo; the church of San Simone; the reconstruction of former Torre dell’Orologio in Piazza Giulio Cesare (1759) (subsequently razed); San Bernardino; and the stairs in the entrance of the Bishop's palace (1750).
