Edmund Roberts (June 29, 1784-June 12, 1836) was an American diplomat.
Appointed by President Andrew Jackson, he served as the United States' first envoy to the Far East, and went on USS Peacock on non-resident diplomatic missions to the courts of Cochinchina, Thailand ("Siam") and Muscat and Oman during the years 1832–6.
Roberts concluded treaties with Thailand and Said bin Sultan, Sultan of Muscat and Oman, ratified in Washington, D.C.
30 June 1834.
He returned in 1836 to exchange ratifications with Oman and Thailand and to the court of Minh M?ng in Cochinchina for a second attempt at negotiation.
He fell seriously ill with dysentery and died in Portuguese Macau, which precluded his becoming America's first envoy to Edo Japan.
