Eugenio José "Bong" Villarreal Lacson (Tagalog: [juˈhɛɲo hoˈsɛ vɪljarɛˈɐl ˈlɐkson]; born December 13, 1959[citation needed]) is a Filipino politician serving as the governor of Negros Occidental since 2019.

[1] He previously served as the province's vice governor from 2013 to 2019, and was the mayor of San Carlos, Negros Occidental from 2001 to 2010.

Bong Lacson served for three consecutive terms as City Mayor of San Carlos, Negros Occidental.

Eventually, he won the polls but his running mate lost to the incumbent Governor Alfredo G. Marañon Jr.[2] Despite belonging to the opposition and holding the majority in the Negros Occidental Provincial Board, he maintained a good relationship with the Governor.

He decided not to run against Governor Marañon, though the governor fielded Rep. Jeffrey Ferrer as his running mate, after failed reunification talks between United Negros Alliance and his coalition, the Love Negros Alliance.
