Gilbert Horal or Erail (died December 1200) was the 12th Grand Master of the Knights Templar from 1193 to 1200.

Gilbert Horal was born an Aragonese (from the Kingdom of Aragon in modern-day Spain), and entered the Templars at a young age.

[1] In 1194, Pope Celestine III gave the Templars more privileges.

[2] Another of Gilbert Horal's accomplishments was that he took the time to organize and consolidate the possessions of the Templars in France and Apulia.

In Spain, the Templars took an active part in the Reconquista, and in 1196 were given the fortress of Alfambra by Alfonso II of Aragon as a reward for their efforts in the battles.
