The Salt actress met with HALO campaigners in Dumfriesshire, Scotland to endorse the organisation's attempts to defuse landmines in war-torn regions.
Jolie said of her visit: "It was a privilege to visit the HALO headquarters and meet their committed staff. In the aftermath of war, HALO's mine-clearing efforts are fundamental to a safe return and community building."
The HALO Trust has destroyed more than one million landmines around the world since it was founded in 1988.
Jolie has been an ardent supporter of landmine removal and recently met with Croatian President Ivo Josipovic to discuss his country's minesweeping efforts.
The actress is currently living with partner Brad Pitt in Scotland while the actor films the upcoming horror movie World War Z.
Jolie's directorial debut In the Land of Blood and Honey opens on December 23 in US cinemas.
