An election for governor was held in the Mexican state of Colima on 6 July 2003, simultaneously with federal congressional midterm elections. Gustavo Vázquez Montes of the Institutional Revolutionary Party (PRI) was initially declared the winner, with 83,995 votes; second place went to the National Action Party (PAN) with 69,180, with the Party of the Democratic Revolution (PRD) in third place with 32,042. Following accusations of irregularities, the gubernatorial result was declared void by the state electoral authorities and an extraordinary election was held on December 7, 2003. Meanwhile, Carlos Flores Dueñas of the PRI served as interim governor.
