Jeanina is of Latin origin, meaning "graced by God" or "god is gracious". It is a variant spelling of the French name Jeannine, which itself is a diminutive of Jean, the French form of John. The name gained popularity in the mid-20th century and has since been used consistently, though not as commonly as its cousin names like Jean or Jeanne. In some cultures, Jeanina may also be associated with the Greek name Ianeira, which means "violet flower". The name has a soft, feminine sound, with the 'ina' ending being particularly popular in female names of this era. It is often spelled Jeanine or Jeannine, and can also have variant spellings such as Gianina, Gianine, or Janina. Some notable figures with these names include Jeannine Oppewall, an American film editor, and Jeanine Hennis-Plasschaert, a Dutch politician.
Jeanina saw its popularity peak in the late 70s and early 90s with 7 births each in 1972 and 1993. The name was consistently used throughout the years between 1962 and 1993, with a total of 51 babies named Jeanina during that period.
