Pantaleon Diaz Alvarez (born January 10, 1958) is a Filipino lawyer and politician serving as the Representative of Davao del Norte's 1st district since 2016, previously holding the position from 1998 to 2001.

In January 2001, President Gloria Macapagal Arroyo appointed him acting Secretary of Transportation and Communications, where he served until July 2002.

[12] In 2005, Alvarez along with four other former Department of Transportation and Communications officials were charged with graft before the Sandiganbayan in connection with the construction of Ninoy Aquino International Airport (NAIA) Terminal 3.

[1][13][6][14] Pantaleon Alvarez allegedly used information gained by his position to preempt the bidding process by creating a company called Wintrack which the board awarded a major sub-contract for the project's site development and excavation work.

[15] In finalizing the General Appropriations Act of 2018, Alvarez and his allies deliberately withheld infrastructure funding from the members of the House of Representatives who they found "undesirable".

Various members of the House of Representatives were alarmed and pointed out the dictatorial and vengeful nature of the Duterte administration and the alacrity in the leadership of Alvarez in perpetuating it.

[16] Alvarez has threatened congressmen and various governmental agencies that they would receive zero budget if they didn't support Rodrigo Duterte's plans to supplant the Republic of the Philippines by implementing PDP–Laban's Federal form of Government.

Alvarez stated that he did not care whether the provinces, agencies and local governments affected by his budget cuts would suffer and told the people to blame their representatives instead who refused to follow what Duterte wanted.

Benito Ranque, PDP–Laban deputy secretary general, states that the new members are not even educated or informed of the party's constitution and by-laws, in support of Cuntapay's accusations.

Alvarez has threatened to dissolve the Court of Appeals and to disbar CA Special Fourth Division, Stephen Cruz, Edwin Sorongon and Nina Antonino-Valenzuela, for granting the habeas corpus petition of six Ilocos Norte officials under their custody for the investigation regarding the "Tobacco Funds" issue.

The bill lists irreconcilable differences or severe and chronic unhappiness causing the "irreparable breakdown of marriage" as the possible grounds for its dissolution.

[31] Alvarez has been known for facilitating and endorsing impeachment efforts against Vice President Leni Robredo and Supreme Court Chief Justice Maria Lourdes Sereno.

Alvarez claims that Robredo's act of portraying the country in a bad light is a betrayal of public trust, and thus impeachable.

[34][35] Alvarez also advocates and encourages the killing of criminals, following the Duterte administration's zero tolerance policy on crimes and corruption.

[36] Alvarez has been a vocal critic of the Catholic Church for opposing the death penalty bill and the Duterte's administration's War on Drugs.

[37][38] This led to his calls for pro-death penalty Catholics to change religion,[39] and to propose taxation of Catholic-run schools,[40] despite its expressed exclusion in the Philippine Civil Code.

He reportedly held the stance as early as 2005 when Rodrigo Duterte, then the Mayor of Davao City, have advocates the Christian-majority portion of Mindanao to secede in the event President Gloria Macapagal Arroyo was deposed by a revolution or coup d'etat.

[48] In November 2023, he proposed that Mindanao should push for independence if the national government continues to pursue its claim in the South China Sea dispute.

In his opinion, pursuing the claim will drag Mindanao into an armed conflict if the national government continues its policy regarding China and expressed reluctance on the United States' commitment to side with the Philippines in a potential military confrontation.
