The Vilnius city wall (Lithuanian: Vilniaus miesto gynybinė siena) was a defensive wall around Vilnius, capital city of the Grand Duchy of Lithuania.
It was built between 1503 and 1522 for protection from the attacks by the Crimean Khanate at the beginning of the Muscovite–Lithuanian Wars.
The stone and brick wall was a key element of the defensive system of Vilnius, and was paid for by the city's landowners.
An artillery bastion was built to protect the eastern side of the city.
Some parts of the wall are still visible throughout the Old Town of Vilnius or are going to be restored and displayed.
