The Armistice of Treviso was a ceasefire signed on 16 January 1801, in Treviso, Italy, between French General Guillaume Brune and the Austrians during the War of the Second Coalition. Brune had defeated Austrian General Heinrich von Bellegarde at the Battle of Pozzolo on 25 December 1800 and drove Generals Josef Philipp Vukassovich and Johann Ludwig Alexius von Loudon from a succession of defensive positions in the mountains. Bellegarde retreated to Treviso and prepared for its defence but agreed to a ceasefire. Under the terms the Austrians ceded many towns in northern Italy but retained Mantua. Napoleon desired the city, which was within striking distance of a French force, and as a result was displeased with Brune, who had promised that Mantua would form part of any armistice deal. However, following French victories in Tuscany and Germany, the French were able to negotiate the ceding of Mantua as part of the Treaty of Lunéville of 9 February 1801.

The War of the Second Coalition was the second war targeting revolutionary France by many European monarchies, led by Britain, Austria, and Russia and including the Ottoman Empire, Portugal, Naples and various German monarchies. Prussia did not join the coalition, while Spain supported France.
