Tiana or Tianna is a feminine given name with various origins. It has been used as an extended form of the name Tia or a short form of names such as Cristiana.[1] In the case of Vietnamese-American actor and director Tiana Alexandra, the name was an English spelling of her Vietnamese language given name, Thi Thanh Nga.[2] It is also a Malagasy unisex name meaning loved in use in Madagascar.[3] The word tiana also has different Māori language origins. Tiana was among the most popular names for Māori girls in New Zealand in 2020.[4] [5] Usage of the name in the United States increased after 1975, which coincided with film and television appearances by Alexandra. Usage of the name also increased after it was used for the main character of the 2009 Disney film The Princess and the Frog.[6][7]
