If there was once a bias against this charming and venerable Italian name for possibly sounding too feminine, consider it gone. Since Luca entered the boys’ names U.S. popularity list in 2000, it has shot up in popularity. It's one of the top Italian baby names in the US and a popular choice throughout Europe as well.

Very much a boy's name in Italy, it's beginning to be seen as a unisex possibility here: actress Jennie Garth used it for her daughter. When spelled Lucca as in the Italian city, it can also be considered one of the place names along with Venezia, Roma, and Milana that make great Italian names for girls.
