Nativity is a term that is used in astrology to refer to the birth chart or natal chart of an individual, which is a diagram that depicts the alignment of the planets at the moment they were born.

The term is derived from the Greek term genesis (γένεσις), which means source, origin, birth, or nativity.

The Greek term was commonly used in Hellenistic and Roman era astrological texts to refer to the birth chart of an individual, or sometimes to refer to the natives themselves.

The English term nativity became common in astrological texts from the 17th century onward, although in modern times the term has become somewhat antiquated, with astrologers usually using the terms birth chart or natal chart instead.
