Thelegislative districts of Southern Leyte are the representations of theprovince ofSouthern Leyte in thevarious national legislatures of thePhilippines. The province is currently represented in thelower house of theCongress of the Philippines through itsfirst andsecond congressional districts.

Prior to gaining separate representation, areas now under the jurisdiction of Southern Leyte were represented under the undivided province ofLeyte (2nd and3rd districts, 1907–1931;3rd district, 1931–1961).

Republic Act No. 2227, enacted on May 22, 1959, created the province ofSouthern Leyte from the southern municipalities of Leyte that constituted itsthird congressional district.^[1] Per Section 5 of R.A. 2227, the incumbent representatives of all five districts of Leyte continued to serve for the remainder of4th Congress. Southern Leyte began to elect a separate representative under its own name starting in the1961 elections.

Southern Leyte was represented in theInterim Batasang Pambansa as part ofRegion VIII from 1978 to 1984. The province returnedone representative, elected at-large, to theRegular Batasang Pambansa in1984.

Under the new Constitution which was proclaimed on February 11, 1987, the province constituted a lone district^[2] which elected its member to the restoredHouse of Representatives startingthat same year.

The signing of Republic Act No. 11198 on February 1, 2019^[3] reapportioned Southern Leyte into two legislative districts. Given that it was already too late for theCommission on Elections to change the old congressional district configuration data in the automated election system in time for theMay 2019 polls, COMELEC Resolution No. 10524 was promulgated to delay the elections for the two new districts to a date no less than six months from May 13, 2019.^[4] By virtue of COMELEC Resolution No. 10552, the date of the elections for thefirst andsecond districts of Southern Leyte was set for October 26, 2019.^[5]

On October 10, 2019, the COMELEC regional office forEastern Visayas suspended the special elections and delayed it to November 30, pending theSupreme Court of the Philippines issuing a certificate of finality in a related case in which COMELEC was found to violate the law by setting separate special elections for the reconfigured1st Congressional District of South Cotabato and the newly createdLone Congressional District of General Santos City instead of the next regular (i.e., 2022) election.^[6][7]

Ultimately, no special elections were carried out. Instead, on December 11, 2019, COMELEC — taking into account the September 10, 2019 Supreme Court ruling on the South Cotabato case (Vice Mayor Shirlyn L. Bañas-Nograles, et al. Vs. Commission on Elections^[8]) — adopted the recommendation of its legal department to direct the Special Provincial Board of Canvassers for the Province of Southern Leyte to count the votes cast in the May 2019 elections.^[9] Roger Mercado was certified as the duly elected representative on December 16, 2019 by the Southern Leyte Provincial Board of Canvassers, and took his oath as the representative of the Lone Congressional District the next day.^[10]

The1st and2nd districts began electing their own representatives starting from the2022 elections.

Southern Leyte's current congressional delegation is composed of two members.
