Andrea is a given name common in many parts of the world:

It derives from the Greek ανήρ (anēr), genitive ανδρός (andrós), that indicates the man as opposed to the woman (while man in the meaning of human being is άνθρωπος, ánthropos, ανθρώπου, anthrópou); ανήρ might be related with the Indo-European root ner which means man, vital force.^{[citation needed]} The original Greek name, Andréas, represents the hypocoristic, with endearment functions, of male Greek names composed with the andr- prefix, like Androgeos, Androcles, Andronikos.

In the year 2006, it was the third most popular name in Italy with 3.1% of newborns. It is one of the Italian male names ending in a, with others being Elia (Elias), Enea (Aeneas), Luca (Lucas), Mattia (Matthias), Nicola (Nicholas), Tobia (Tobias).

It is traditionally popular because, according to the Christian Bible, Saint Andrew was one of the earliest disciples of Jesus and one of the twelve Apostles.
