The Portrait of Lucrezia Panciatichi is an oil on panel painting by the Italian artist Agnolo di Cosimo, known as Bronzino, finished around 1545.

Lucrezia di Sigismondo Pucci was the wife of Bartolomeo Panciatichi, a Florentine humanist and politician.

[citation needed] The refined garments and jewelry reflect her elite social position and aspects of her identity as a devoted wife.

The words "Amour dure sans fin" ("love endures without end") appear on her golden necklace.
