Fort Mosta (formerly written as Fort Musta,Maltese: Il-Fortizza tal-Mosta) is a polygonal fort in Mosta, Malta. It was built between 1878 and the 1880s by the British as part of the Victoria Lines. It is still in use today by the Armed Forces of Malta as an ammunition depot.

Fort Mosta was built by the British as part of the Victoria Lines, a line of fortifications along the northern part of Malta, dividing it from the more heavily populated south. It is one of three forts built along the lines, the other two being Fort Binġemma and Fort Madalena.

The fort is the most strategically placed land fort along the Victoria Lines, occupying the cliff face at the mouth of Wied il-Għasel. According to Giorgio Grognet de Vassé, the site has had strategic value since ancient times and it was previously occupied by a Bronze Age citadel and village, and there were archaeological remains there. When the British requisitioned the site to build the fort, they probably destroyed the Bronze Age remains, although no actual proof of their existence is known. Despite this, catacombs dating to the 4th or 5th century AD were found under the fort and they still exist.

The fort was last of the three major forts of the Victoria Lines to be built. Its construction was approved in 1873, but while construction the other forts begun in 1875 (Fort Binġemma) or 1878 (Fort Madalena), work on Fort Mosta had not commenced by the visit of General Lintorn Simmons (who later became Governor of Malta in 1884) in February 1878. Construction began soon after his visit.

The fort consists of two parts, a pentagonal keep, which is surrounded by a ditch, and a battery outside the keep. These were linked together with a sally port. Unlike the two other forts, Fort Mosta did not have RML guns since it was not intended for coastal defence. It was initially armed with 64-pounder smooth-bore muzzle loading guns, but later 6-inch breech-loading guns were installed.
