Beleg is a fictional character from J. R. R. Tolkien's universe of Middle-earth.

Beleg was the son of King Amlaith of Arthedain.

During his reign hobbits were first seen west of the Misty Mountains and Sauron returned to Mirkwood and thus returning to Middle-earth.

He died in 1029 T.A. and was succeeded by his son Mallor.
