The Battle of Buçaco (pronounced: [buˈsaku]) or Bussaco, fought on 27 September 1810 during the Peninsular War in the Portuguese mountain range of Serra do Buçaco, resulted in the defeat of French forces by Lord Wellington's Anglo-Portuguese Army.

Having occupied the heights of Bussaco (a 10-mile (16 km) long ridge located at 40°20'40"N, 8°20'15"W) with 25,000 British and the same number of Portuguese, Wellington was attacked five times successively by 65,000 French under Marshal André Masséna. Masséna was uncertain as to the disposition and strength of the opposing forces because Wellington deployed them on the reverse slope of the ridge, where they could neither be easily seen nor easily softened up with artillery. The actual assaults were delivered by the corps of Marshal Michel Ney and General of Division (Major General) Jean Reynier, but after much fierce fighting they failed to dislodge the allied forces and were driven off after having lost 4,500 men against 1,250 Anglo-Portuguese casualties.

In 1810, Emperor Napoleon I ordered Masséna to drive the British from Portugal. Accordingly, the French marshal began the Siege of Ciudad Rodrigo in April. The Spanish garrison held out until 9 July when the fortress fell. The Battle of the Côa was fought soon after. The Siege of Almeida ended suddenly with a massive explosion of the fortress magazine on 26 August. With all obstacles cleared from their path, the French could march on Lisbon in strength.
