Corraine is a rare and distinct given name with unknown origins, first appearing in England during the 16th century. While its etymology and meaning remain unclear, theories suggest it may be a diminutive of Coralyn or Coralie, or originally a surname adopted as a given name. It has been associated with royalty, notably Lady Corraine Hamilton, who served Queen Mary II. Today, Corraine is considered an attractive yet uncommon choice for baby girls in the United States.
