Joal is an uncommon given name of Hebrew origin, meaning "Jehovah is Lord". It is often considered a variant spelling of Joel, but it has its own unique identity. This name was popularized by the Old Testament prophet Joel, whose book is one of the twelve minor prophets in the Hebrew Bible. The name Joal, like Joel, evokes a sense of divine presence and lordship.
The name Joal saw a spike in popularity between 1946 and 1986 with peaks in the late 70s and early 80s, before declining to consistent low numbers by the turn of the century.
