The siege of Shimabara Castle (December 12, 1637-January 8, 1638) was an unsuccessful siege of the Shimabara Castle by rebel peasants and ronin during Shimabara Rebellion. Although the castle garrison was too weak to defend the castle town, which was completely looted and burned down, the numerically superior rebels were not able to storm the heavily fortified citadel. After a siege that lasted for 20 days, the news of an upcoming Shogunate army forced the rebel forces to retreat to the south, where they fortified themselves in the dilapidated Hara Castle.
