The Vasari Sacristy or Old Sacristy is a room in Sant'Anna dei Lombardi, Naples, Italy, one of its two sacristies. It was the refectory of the Olivetan monastery of Santa Maria di Monteoliveto until 1688, when it was converted to its current role. The conversion in 1688 revealed 15th century inlays by Fra Giovanni da Verona, also to be seen in the church's Tolosa Chapel. The church was renamed Sant'Anna dei Lombardi in 1805.
An Adoration of the Shepherds by a follower of Vasari was moved to its present position above the door in the counter-facade during the 17th century. The two side lunettes contain sculptures of the archangel Gabriel and the Virgin Mary, attributed to Giovan Battista Cavagna and resting on two marble lavabos leaning against the walls.
The central nave vault is divided into three quadrants, showing personifications of Faith, Religion and Eternity It is accompanied along the walls by 17th century furniture decorated with a cycle of precious wooden inlays by Fra Giovanni da Verona dating to 1506 with views of the city and scenes of life in the Olivetan order. Between the inlays are niches with wooden statues showing saints relating to the Olivetans. Behind the altar is a painting of Carlo Borromeo by Girolamo d'Arena, which had hung in the original church of Sant'Anna dei Lombardi but was moved to its present location after that church was destroyed in the 1805 earthquake. Either side are two paintings of Michael the Archangel and the Virgin Mary.
