Local elections were held in Marinduque on May 13, 2019, as part of the 2019 Philippine general election. Voters selected 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 sought reelection, including incumbent congressman Lord Allan Jay Velasco. This was the first election since the 1970s where Carmencita Reyes, who had previously served both as congressman and governor, did not running for office, having died in January 2019.
Romulo Bacorro assumed office after the death of Carmencita Reyes. He ran for his old position of Vice Governor in this election as the running mate of former Associate Justice Presbitero Velasco Jr. On May 3, Violet Reyes withdrew from the race.
Mark Anthony Seño, who assumed the position after Romulo Bacorro became governor, ran for town councilor in Boac as he was ineligible to run for reelection as provincial board member after serving his third term in office.
Lord Allan Jay Velasco was reelected.
