Robert Sidney Gelbard (born March 6, 1944) is an American diplomat and former United States Ambassador to Bolivia (1988–1991) and Indonesia (1999–2001).

[1] By May 1998, he suggested to the White House that they bomb Serbia, but the idea was originally rejected by NSA Sandy Berger.

In October 2011, the Economist reported that Gelbard lobbied to discredit the International Commission against Impunity in Guatemala and its current director, Francisco Dall'Anese.

Dall'Anese suggested that the lobbying campaign was funded by private sector opponents of the Commission's investigation of Guatemala's wealthy former interior minister, Carlos Vielmann, on charges of orchestrating extrajudicial killings.

[6] In response to the accusations concerning the International Commission against Impunity in Guatemala, Gelbard wrote in The Economist: "Based on two decades of experience in democratic institution-building, law enforcement and counter-narcotics, I have criticised the overall efforts of Francisco Dall'Anese, who heads CICIG, as being not aggressive enough compared with those of Carlos Castresana, his predecessor, and in light of the dire situation facing Guatemala.
