Edgar "Pop" Buell (April 26, 1913 – December 30, 1980) was a humanitarian aid worker in Laos. He worked as a farmer in Steuben County, Indiana until the age of 47, but following the death of his wife in 1958 he joined the International Voluntary Services, a precursor to the Peace Corps, which offered him a job as an agricultural adviser in Laos. Buell worked in Laos through the Laotian Civil War, organizing relief aid to refugees and isolated villages. He was forced to flee Laos in 1974 when the Communist Pathet Lao gained control of the country.
