The second siege of Porto Alegre was a siege carried out by rebel forces during the Ragamuffin War in southern Brazil between March 1837 and February of 1838. It was the second out of three sieges to Porto Alegre, the capital of Rio Grande do Sul, during the conflict. Porto Alegre had been in Imperial hands ever since June 1836 (when it was recaptured).

After a long recovery period after the rebel defeat at the Battle of Fanfa, their commander Antônio de Sousa Neto marched towards the city with 1,400 men, and over the course of little less than a year assaulted the city several times, eventually being forced to withdraw by the defenders who were gradually reinforced.
