Legislative district of Dinagat Islands

The Legislative district of Dinagat Islands is the representation of the province of Dinagat Islands in the of the Philippines. The province is currently represented in the lower house of the Congress of the Philippines through its lone congressional district.

Prior to gaining separate representation, areas now under the jurisdiction of Dinagat Islands were initially represented under the former province of Surigao (1907–1961) and Surigao del Norte (1961–2007). The passage of Republic Act No. 9355 on 2 October 2006, and its subsequent ratification by plebiscite, separated the seven municipalities of the new province of Dinagat Islands from Surigao del Norte's first district. The new province elected its separate representative beginning in the 2007 elections.

Despite Dinagat Islands being nullified as a province by the Supreme Court of the Philippines on 11 February 2010 the decision was not yet rendered final and executory before the 10 May 2010 elections; therefore the Commission on Elections still organized the elections for Dinagat Islands' congressional representative along with its provincial officials. Even after the Supreme Court rendered its original decision final and executory on 18 May 2010, the representatives of the reconfigured first district of Surigao del Norte and the lone district of Dinagat Islands continued to represent their own constituencies.
