2022 San Mateo, Rizal, local elections
Local elections were held in San Mateo, Rizal, on May 9, 2022, as part of the Philippine general election. Held concurrently with the national elections, the electorate voted to elect a mayor, a vice mayor, eight members of the municipality's municipal council, a board member to the Rizal Provincial Board, and a representative to the House of Representatives. Those elected assumed their respective posts on June 30, 2022, alongside other local and national officials. 92,805 of 110,276 registered voters voted in these elections. Omie Rivera and Jimmy Roxas were elected to the mayoralty and vice mayoralty respectively, ending the Diaz family's longstanding hold on the municipality's mayoralty. Despite their mayoral loss, 1SanMateo won an outright majority in the municipal council, winning six of the eight elective seats. The remaining two seats were won by members of Team I Love San Mateo. This election was the first to utilize the newly created Rizal's 3rd congressional district, which gave the municipality its own representation in the House of Representatives and the Rizal Provincial Board. Jose Arturo Garcia Jr. and John Patrick Bautista won their respective races to represent the district as a representative and as a board member respectively. Background 

In the 2019 elections, Tina Diaz and her husband Jose Rafael Diaz were re-elected to the municipality's mayoralty and vice mayoralty respectively, with Tina defeating Independent Wilfredo Selga and Jose Rafael being unopposed in the vice mayoral race. The Diaz family has controlled the municipality's mayoralty for decades at that point. On March 25, 2022, President Rodrigo Duterte signed Republic Act 11533 into law, thereby separating the municipalities of San Mateo and Rodriguez from the province's second district to create its third and fourth districts. The law took effect on April 12, 2022, though the second district remained intact until the election and subsequent inauguration of the representatives for the new districts. Juan Fidel Felipe Nograles remained as the second district's representative until the end of the 18th Congress; he was redistricted to the fourth district after the division. On August 20, 2020, both Tina and Jose Rafael Diaz tested positive for COVID-19; Municipal Administrator Ricardo Gomez was designated as the alternate signatory to all official municipal transactions as Diaz recovers from the disease. MMDA General Manager Jose Arturo Garcia resigned his post as general manager on October 4, 2021 in order to run for representative. Coalitions 
As the mayor, vice mayor and the members of the municipal council are elected on the same ballot, mayoral candidates may present or endorse a slate of candidates. These slates usually run with their respective mayoral and vice mayoral candidates along with the other members of their slate. A group of candidates independent of any mayoral or vice mayoral candidate may also form a slate consisting of themselves. Administration coalition

House of Representatives election 

On March 25, 2021, Rizal's 2nd congressional district—which then included San Mateo—was split into three districts, with the third solely encompassing San Mateo. The second district in its previous form was last represented by Juan Fidel Nograles, who was re-elected in 2019 with 69.01% of the votes within the municipality. Nograles, who hails from Rodriguez, was redistricted to the fourth district, leaving the third district with an open race as a result. The field to fill the open seat included three candidates. Incumbent Mayor Tina Diaz was nominated by the PDP–Laban to run for the seat, with the support of the ruling 1SanMateo coalition. Meanwhile, Team I Love San Mateo nominated Former Metropolitan Manila Development Authority General Manager Jose Arturo Garcia to challenge Diaz for the seat.

Provincial board election 

The second district in its previous form was represented in the Rizal Provincial Board by incumbents Rommel Ayuson, Omie Rivera, Rolando Rivera, and Dino Tanjuatco, who were all re-elected in 2019. Following the creation of the third district—which solely encompasses San Mateo—the municipality is represented by one board member elected by the district. Among the four incumbents, Ayuson and Tanjuatco ran for public office in other districts; Omie Rivera ran for the Mayoralty of San Mateo; and Rolando Rivera was term-limited, later dying in office on March 24, 2022. Thus, the third district was left with an open race for its provincial board seat. The ruling 1SanMateo coalition nominated Hermenegildo Cequeña for the seat, while Team I Love San Mateo nominated John Patrick Bautista for the seat. A third candidate—Cirilo Oropesa Jr.—also ran for the seat. Candidates
