Luca Pitti (1398–1472) was a Florentine banker during the period of the republic presided over by Cosimo de' Medici.

In August, 1458, he staged a coup to seize control of Florentine government in the name of its existing ruler, the elderly and now frail Cosimo de' Medici.

The newly formed government was to last eight years with Cosimo as its figurehead, the reality being he was too frail to maintain power alone.

Pitti was then ennobled and very wealthy indeed, Niccolò Machiavelli in his History of Florence estimates no less a sum than twenty thousand ducats was presented to him.

However the family survived the upheaval following the overthrow of the Medici's power in 1494, and the tyrannical and puritanical rule of Girolamo Savonarola.
