The Second Chamber of Deputies of the Ottoman Empire was elected in the second 1877 Ottoman general election. The parliament served from 13 December 1877 to 14 February 1878.
Coinciding with the Russo-Turkish War of 1877-1878, the Parliament set aside legislative matters to discuss government actions and the management of the war. Worried about increasing opposition to his government, Abdulhamid II suspended the Chamber of Deputies indefinitely on 14 February 1878 with the excuse of war-time necessities, based on the authority granted to him in Article 7 of the constitution and the approval of the Senate.
