Rafael Espuerta Seguis (born October 24, 1939) is a retired Filipino diplomat who served as Philippine ambassador to Indonesia (2002-2003), Saudi Arabia (1999-2002), and Iraq (1991-1996).
He undertook sensitive missions for the Philippine government, notably in the areas of anti-terrorism, maritime and territorial delimitations, the country’s bid for observer status in the Organization of Islamic Cooperation (OIC), and the conduct of overseas absentee voting during national elections.
In 2004, he was tasked to negotiate on two occasions for the safe release of Filipinos held hostage by Iraqi insurgents.
When peace talks with the Moro Islamic Liberation Front collapsed in 2008 and the Philippine negotiating panel had to be reconstituted, Seguis did not demur when asked by then-President Gloria Macapagal Arroyo to head the peace negotiating panel.
His vast experience, an unrelenting capacity for sustained work, and a characteristic low-key approach have earned him a reputation as an indispensable troubleshooter within the Philippine government.
