Bettyjo is a unique, two-part female given name of American origin. It combines "Betty" and "Jo," which were both popular names during the mid-20th century in the United States. The name Betty is derived from the medieval English nickname "Beth" meaning "life," while Jo is short for Josephine or Joseph, both having Hebrew origins with meanings like "Jehovah increases" or "may God increase." Therefore, Bettyjo could be interpreted as "Life increases" or a variation thereof. The name has gained some popularity over time and is often associated with an approachable and friendly demeanor due to its informal nature.
The name Bettyjo appears to have been quite popular during the early and mid-20th century, with a significant number of babies given this name between 1920 and 1970.

Interestingly, there was a resurgence in the use of Bettyjo as a baby name in 2021, with five births registered that year.
