Tudḫaliya is the name of several Hittite kings or royals. It is not clear how many kings bore that name, and numbering schemes vary from source to source.

Some biblical scholars suggested that Tidal, king of Nations (Goyim), who is mentioned in the Book of Genesis 14 as having joined Chedorlaomer in attacking rebels in Canaan is based on one of the Tudhaliyas. In modern academia, Tidal is considered to be a literary figure, not a historical figure. The discussion about Tidal relates to the Battle of Siddim in the Bible; the exact geographical location of Tidal is disputed. 'Tidal, king of Goyim', may also be related to the island kingdoms in Mediterranean Sea.
