Wbaldino Acosta (1938 – 1 August 2007) was an Argentine politician who served as Governor of his province of San Juan.

In 1971 he had joined the important San Juan party, the Partido Bloquista, led by Leopoldo Bravo who served several times as Governor and Senator.

[1] On 16 May 1999, Acosta was elected once again as vice-governor of San Juan accompanying the Renewal Crusade party's Alfredo Avelín who won with 55%, heading the list of the Alliance for Work, Justice and Education which would win the Presidency of Argentina later the same year.

Avelín's period in office was marked by economic turbulence and public unrest in San Juan, like the country as a whole.

He subsequently opposed his party's decision to back Gioja and the national government of Néstor Kirchner.
