Sant'Anna dei Lombardi, (Italian: St. Anne of the Lombards), and also known as Santa Maria di Monte Oliveto, is an ancient church and convent located in piazza Monteoliveto in central Naples, Italy.

[2] The entire complex was at one time one of the largest monasteries in Italy, occupying what today can be measured only in "city blocks".

At the east end, the church, itself, is still in use, but the adjacent monastery premise and courtyard are now a Carabinieri (Italian national police force) barracks.

The church structure is unusual in that the nave has no transept, thus no crossing, but instead has a linear rectangular layout with ten lateral chapels.

The initial plan is attribute to Andrea Ciccione,[3] but it underwent an updated refurbishment in a late Renaissance style by Fontana.
