Ernesto "Ernie" Madarang Maceda Sr. (March 26, 1935 – June 20, 2016) was a Filipino politician, lawyer, and columnist who served as a Senator of the Philippines from 1971 to 1972 and again from 1987 to 1998.

Maceda went into exile in the United States after breaking with President Marcos over the Martial Law declaration and eventually became the adviser of Senator Benigno Aquino Jr.

During the 1992 general elections, Senator Maceda was re-elected under the Nationalist People's Coalition, which was a faction that bolted from the Nacionalista Party, headed by former Tarlac Governor Danding Cojuangco.

In November of that year, Senate President Maceda delivered a speech denouncing the PEA-Amari Scandal – calling the same as the "grandmother of all scams".

[3] The PEA-Amari Scandal was a controversial deal involved the acquisition of 158 hectares of reclaimed land on Manila Bay that was to be converted into so-called Freedom Islands.

In February 1998, months before his second and last term as senator ended, Maceda ran for mayor of Manila in the 1998 presidential elections, but lost to Lito Atienza.

As a result, he was arrested on May 2 during a government crackdown, though authorities released him a few days later to the custody of his lawyer Alfredo Lazaro Jr. for health reasons.

[4][5] In the 2004 elections, Maceda ran for senator under the Koalisyon ng Nagkakaisang Pilipino of presidential candidate Fernando Poe, Jr. but lost.

He wrote a thrice-weekly column for the Philippine Star, entitled "Search for Truth", and hosted his own talk show Mr. Expose on the radio station DZRJ-AM.

Maceda died of multiple organ failure at St. Luke's Medical Center in Quezon City, Philippines on the night of June 20, 2016.
