The 45-year-old "Trainspotting" star will be feted on October 28 by organisers at The British Academy of Film and Television Arts Los Angeles for "using the art form of the moving image... To create positive social change, and actively shine a light on important humanitarian issues", according to The Hollywood Reporter.
"Ewan McGregor is not only a multi-talented individual, but has led by example in showing that even one person can make a huge difference in the life of a child," chairman of BAFTA Los Angeles Kieran Breen said.
In July, the actor travelled to the Debaga camp in northern Iraq to meet children and families displaced by conflict in the country and nearby Syria, and he became emotional as he recalled what he saw to ITV News.
McGregor, a UK ambassador for United Nations Children's Emergency Fund (UNICEF), called the experience "mind-bending" and admitted he had "never felt more confused and upset" meeting families who had lost their homes and possessions, but were still positive because they had each other.
Previous recipients of the Britannia Humanitarian Award include Idris Elba, Richard Curtis, Don Cheadle, Colin Firth, Mark Ruffalo, and Orlando Bloom.
