The Legislative District of Marinduque is the current representation of the Province of Marinduque in the Philippine House of Representatives.
Marinduque was initially represented as part of the second district of Tayabas in 1907, after its annexation as a sub-province of the latter.

The province was represented in the Interim Batasang Pambansa as part of Region IV-A from 1978 to 1984, and elected one representative to the Regular Batasang Pambansa in 1984. Marinduque retained its lone congressional district under the new Constitution which took effect on February 7, 1987, and elected its member to the restored House of Representatives starting that same year.
