The province is currently represented in the lower house of the Congress of the Philippines through its lone congressional district.
In the disruption caused by the Second World War, however, Marinduque was abolished and its municipalities were absorbed by Tayabas once again in 1942 by virtue of Executive Order No.
Thus, it became part of the at-large district of Tayabas during the National Assembly of the Japanese-sponsored Second Philippine Republic from 1945 to 1944.
Upon the restoration of the Philippine Commonwealth in 1945, Marinduque's pre-war representation was retained; this remained so until 1972.
Marinduque retained its lone congressional district under the new Constitution[2] which took effect on February 7, 1987, and elected its member to the restored House of Representatives starting that same year.
