The HALO Trust is a UK-based charity organization that specializes in the removal of landmines, unexploded ordnance (UXO), and other explosive remnants of war. The organization was founded in 1988 by Guy Willoughby and Colin Campbell Mitchell, and it is headquartered in Thornhill, Scotland.

The HALO Trust works in various countries and regions around the world, including Africa, Asia, the Middle East, and Latin America. The organization’s primary focus is on removing landmines and other explosive hazards from conflict-affected areas, in order to reduce the risk of injury and death to civilians and to enable affected communities to rebuild and develop their economies and infrastructure.

In addition to mine clearance, the HALO Trust also provides risk education and mine awareness training to local communities, and works with governments and other organizations to advocate for the ban of landmines and other indiscriminate weapons.

Over the years, the HALO Trust has received support from various sources, including governments, foundations, and private donors. The organization has been recognized for its work with numerous awards, including the Nobel Peace Prize in 1997, which was awarded jointly to the International Campaign to Ban Landmines (ICBL) and its founding coordinator, Jody Williams.
