Humberto Moreira Valdés (born 28 July 1966) is a Mexican politician who served as President of the Institutional Revolutionary Party.

As of 23 August, it was revealed that during his administration, the debt of the state increased more than hundred-fold, amidst allegations of opacity in the management of public finances.

[5] During his tenure as governor of Coahuila, Moreira signed decrees where the state acquired a debt of over thirty-three hundred billion pesos, he was accused of using fake documentation to obtain the money, and it is presumed that was used to illegally finance, and win, 5 governorships for the PRI party, and also to finance the campaign of current President Enrique Peña Nieto.

[9] On 30 June 2015 a state court in Texas related Moreira with money laundering operations through the use of an intermediary called Rolando Gonzalez Trevino, who agreed to plead guilty and implicated the ex-governor.

According to this statement, in 2006, Moreira and other senior officials of the state of Coahuila took public funds from the treasury, and transferred them to Gonzalez Treviño to invest in the acquisition of radio stations.

[2][10][11] It was reported that the Spanish government's anti-corruption prosecutor was investigating the relation between Moreira's money laundering operation[12] and los Zetas drug cartel,[13] [14] and stated that the assassination of Moreira's son in 2012, was in retaliation of a money laundering operation where the Los Zetas cartel did not get their share.

He married three times and is father of five children: José Eduardo, Rubén Humberto, Alba Elena, Joaquín Felipe and Vanessa Lucìa.
