Gia is a cute if slight name that calls to mind stylish sisters Mia, Lea, Pia, Tia, and Nia. Gia is a short form of Gianna, which in turn is a diminutive of Giovanna, the feminine form of Giovanni, the Italian equivalent of John—all of them meaning "God's gracious gift."
Gia first made a strong impression via Gia Carangi, the ill-fated supermodel whose biopic provided Angelina Jolie's breakout role in 1998. It entered the Top 1000 in 2000, and has been rising ever since.
Gia was chosen by Matt Damon and by Mario Lopez for their daughters and also gained recent fame as the name of the oldest daughter of Real New Jersey Housewife Teresa Giudice.
