Harry George Barnes Jr.[1][2] (June 5, 1926 – August 9, 2012) was an American diplomat, known for his role in ending the government of Chilean dictator Augusto Pinochet.

[4] Barnes served as Deputy Chief of Mission in Bucharest in 1968–71, during which time he became the first American diplomat to address the Romanian nation on television.

[3] After returning to Washington he served as supervisory personnel officer (1971–72) and deputy executive secretary (1972–74) before being named Ambassador to Romania by Richard Nixon.

[5] Although the American government, in particular Henry Kissinger, had supported the rise of dictator Augusto Pinochet, by 1985 the Chilean opposition started to campaign against extending his rule.

"[3] In addition to agitating for democratic reform, Barnes contributed oversight to the 1988 Chilean national plebiscite against extending Pinochet's rule, funding a parallel vote tally and advertising for the anti-Pinochet campaign.
