The Revolt of the Faitiões (Chinese: 十·八慘案; Portuguese: Revolta dos faitiões) was an armed insurrection against Portuguese rule in Macau that took place on 8 October 1846. The revolt was prompted by a duty imposed on the faitiões ("fast boats [junks]", from Chinese fai teang) by the new governor. João Maria Ferreira do Amaral had been appointed governor of Macau on 21 April 1846 in the aftermath of the First Opium War, when the Portuguese wanted to assert their rights against a weak and defeated China and resist British power.
