2010 Philippine House of Representatives elections in the Ilocos Region

Elections were held in the Ilocos Region for seats in the House of Representatives of the Philippines on May 10, 2010.

The candidate with the most votes won that district's seat for the 15th Congress of the Philippines.

Ilocos Norte
In Ilocos Norte, the Marcoses had a split within their ranks, former first lady Imelda Marcos and her children Bongbong and Imee Marcos had allied themselves with Nacionalista Party and then-Senator Manny Villar. Imelda's nephew Michael Marcos Keon would only support Bongbong's campaign for senator as part of the Nacionalista's roster but not Villar; Marcos Keon is a member of Lakas-Kampi-CMD and supports Gilbert Teodoro. The Marcoses also had a reconciliation with the Fariñases and invited Rodolfo Fariñas as a congressional candidate for the Nacionalistas in the province's first district.

1st District
Incumbent Roque Ablan, Jr. (Lakas-Kampi-CMD) is on his third consecutive term and can not run for reelection. His seat will be contested by his son Kristian and former congressman Rodolfo Fariñas.

The result of the election is under protest in the House of Representatives Electoral Tribunal.

2nd District
Incumbent Bongbong Marcos will leave the House to run for a Senate seat. His mother and former first lady Imelda will run for his seat under the Kilusang Bagong Lipunan (KBL) as the younger Marcos was expelled from the party. She was challenged by Marcos supporter Mariano Nalupta. She is co-nominated by the Nacionalista Party.

Nalupta placed the result of the election under protest in the House of Representatives Electoral Tribunal.

Ilocos Sur
In Ilocos Sur the Singson clan headed by Luis Singson is expected to win majority of elective positions in the province. Luis will run as governor of the province, his son Ronald Singson will run as the province's representative from the first district, and daughter-in-law Grace Singson will run on her husband Eric Singson's seat in the second district since Eric is limited three consecutive terms. Eric and Grace's son Eric Jr. was Lakas-Kampi-CMD's nominee in the district.

1st District
Ronald Singson is the incumbent.

In March 2011, Singson resigned after being found guilty of drug possession in Hong Kong. The Commission on Elections called an election that will be held on May 28, 2011.

2nd District
Eric Singson is the incumbent, but he is in his third consecutive term already and is ineligible for reelection. His son Eric Jr. is his party's nominee for the district's seat.

La Union
La Union's two seats in the House will be contested in albeit different circumstances: in the first district, Rep. Victor Francisco Ortega, whose brother is the current Governor Manuel Ortega will contest the seat against an independent candidate James Paul Orros, who claims to be a relative of the Ortegas. In the second district, Butch Dumpit, son of defeated gubernatorial candidate Tomas Dumpit in 2007, will go up against Eufranio Eriguel, who reportedly has support by nine of the eleven mayors in that district. The younger Ortega and Dumpit will contest the province's governorship anew.
