The siege of Rennes was an episode in the War of the Breton Succession during 1356-1357.

It was the third siege of the town during that war: between April and mid-May 1341, Rennes was besieged by Jean of Montfort, who finally managed to capture it. The city was repaired the following year by Blesist troops after several days of siege. Between the two events, Rennes had kept itself apart from the conflicts, until after the battle of Poitiers, when Henry of Grosmont, duke of Lancaster, came to besiege Rennes in October 1356, hoping thus to precipitate the end of the War of Succession.
