The Siege of Perth was conducted from June to August 1339 as part of the Wars of Scottish Independence. The siege was conducted by forces loyal to David II of Scotland and commanded by Robert Stewart, the Guardian of Scotland. The defending forces were acting on behalf of Edward Balliol and were commanded by Thomas Ughtred.

Balliol had invaded Scotland in 1332 with the support of Edward III of England, taking advantage of the fact that Scotland had no strong leader following the death of Robert Bruce, to press his own claim to the throne. Balliol was crowned at Scone and from 1333 his regime was based in Perth. An English garrison was based in the town from 1335. From 1338 Stewart was Guardian of Scotland and was targeting the areas of Scotland sympathetic to the Balliol cause.

Ughtred was forced to surrender on 17 August after 10 weeks of siege, during which the attacking force had deployed a group of barges to the Tay estuary to prevent supplies arriving by water.
