Toron, now Tibnin or Tebnine in southern Lebanon, was a major Crusader castle, built in the Lebanon mountains on the road from Tyre to Damascus.

It was the centre of the Lordship of Toron, a seigneury within the Kingdom of Jerusalem, actually a rear-vassalage of the Principality of Galilee. The castle was built by Hugh of Falkenberg, second prince of Galilee, in 1105 to help capture Tyre. After Hugh's death it was made an independent seigneury, given to Humphrey I before 1109.

After Humphrey I of Toron, the castle and lordship of Toron successively passed to his descendants Humphrey II and Humphrey IV. Banias, which had been given to Baldwin II by the Assassins in 1128, was inherited by Toron around 1148 when Humphrey II married the daughter of Renier Brus, lord of Banias and Assebebe. Humphrey II sold parts of Banias and Chastel Neuf to the Knights Hospitaller in 1157. Banias was merged with Toron until it fell to Nur ad-Din Zangi on 18 November 1164, and when it was recovered it became part of the Seigneury of Joscelin III of Edessa (see below).
