The name Kianna is a feminine given name of Greek origin, derived from the word "kianos," meaning "blue" or "sky-colored." It is believed to have emerged in the late 20th century, likely as a combination of the names Kia and Anna.

The earliest recorded use of the name Kianna dates back to the 1970s, though it did not gain widespread popularity until the late 1990s and early 2000s. Some of the earliest known bearers of the name include Kianna Wibunsin, a Thai actress born in 1971, and Kianna Aaliyah, an American singer and songwriter born in 1984.

In ancient Greek mythology, the name Kianna may have been associated with the goddess Kyanê, a minor deity who personified the color blue. However, there is no direct historical evidence linking the modern name Kianna to this mythological figure.

Throughout history, several notable individuals have carried the name Kianna. One of the most famous is Kianna Dior, an American reality television personality and model who rose to prominence in the early 2010s. Another is Kianna Naomi, an American singer and songwriter who has released several albums since the late 2000s.

Other noteworthy individuals with the name Kianna include Kianna Bradley, an American basketball player who played for the University of Connecticut in the early 2000s, and Kianna Ziz, a Canadian actress and model known for her roles in various television shows and films in the 2010s.

While the name Kianna has Greek roots, it has gained popularity across various cultures and regions, particularly in North America and Europe, in recent decades. Its association with the color blue and its melodic sound have contributed to its appeal as a modern and unique given name.
