Local elections were held in Marinduque on May 13, 2019 as part of the 2019 Philippine general election. Voters will select candidates for all local positions: a town mayor, vice mayor and town councilors, as well as members of the Sangguniang Panlalawigan, a vice-governor, a governor and a representative for the lone district of Marinduque in the House of Representatives.
In this election, a number of provincial-level officials are seeking reelection, including incumbent congressman Lord Allan Jay Velasco. Notably, this is the first election since the 1970s where Carmencita Reyes, who had previously served both as congressman and governor, is not running for office, having died in January 2019.
Romulo Bacorro assumed office after the death of Governor Carmencita Reyes. Instead of running for governor, he is instead running for his old position of Vice Governor in this election as the running mate of former Associate JusticePresbitero Velasco Jr. On May 3, Violet Reyes withdrew from the race.
Mark Anthony Seño, who assumed the position after Romulo Bacorro became governor, is running for town councilor in Boac as he is ineligible to run for reelection as provincial board member after serving his third term in office.
Incumbent Russel Madrigal is ineligible to run for reelection as mayor after serving his third term in office. His wife, Nancy Madrigal, is running in his stead.
