The province is currently represented in the lower house of the Congress of the Philippines through its lone congressional district.
From 1907 the sub-province Siquijor was represented as part of the second district of Negros Oriental.
Negros Oriental and the sub-province of Siquijor were represented in the Interim Batasang Pambansa as part of Region VII from 1978 to 1984.
Siquijor's first representative was elected in 1984, after it was established as a regular province on September 17, 1971 through Republic Act No.
Siquijor retained its lone 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.
