The Republic of Lucca (Italian: Repubblica di Lucca) was a medieval and early modern state that was centered on the Italian city of Lucca in Tuscany, which lasted from 1160 to 1805.

Its territory extended beyond the city of Lucca, reaching the surrounding countryside in the north-western part of today's Tuscany region, to the borders with Emilia-Romagna and Liguria.

The Republic of Lucca remained independent until 1799. Later the state continued to exist but was, de facto, dependent upon Napoleonic France, and ceased officially its existence in 1805, when it was transformed in the Principality of Lucca and Piombino.
