Palazzo Lanfreducci, Historic palace on Lungarno Pacinotti, Pisa, Italy.

Palazzo Lanfreducci is a Renaissance-era palace stretching across three floors along Lungarno Pacinotti in central Pisa. Its facade combines marble and local Verrucano stone with windows, a prominent balcony above the main entrance, and carved decorative details.

Battista Lanfreducci, of a Pisan family documented since the 13th century, commissioned the palace; its present form was designed by Sienese architect Cosimo Pugliani from 1594 into the early 1600s. English sources instead date construction from 1607 for Francesco Lanfreducci, a Knight of Malta back from imprisonment in Algeria. In the 19th century the building passed to the Upezzinghi, who gave it their name.

The name "alla Giornata" comes from the motto chosen by Francesco Lanfreducci, a Knight of Malta: literally "on the day of battle", a challenge to a rival in the Order's late-16th-century power struggle. Three chain links above the main door are popularly linked to his imprisonment in Algiers. The palace is named in D'Annunzio's poem I camelli.

The building sits along the Lungarno Pacinotti, directly on a busy riverfront stretch, making it easy to reach on foot from most central locations. A nearby bus stop serves multiple lines, and the railway station is reachable by walking along the riverside.

The motto 'Alla Giornata' literally means 'on the day of battle', a challenge to a rival who had bested Lanfreducci unfairly in the power struggles of the Order of Malta in the late 16th century. The chain links above the portal allude to his imprisonment in Algiers, and D'Annunzio mentions the palace and its inscription in his poem I camelli.
