Maternity is everything to do with becoming and being a mother. Pregnancy, birth, and the months after.
The word appears mainly as a modifier, so maternity leave, a maternity ward, maternity clothes and maternity pay are all standard, and each is a piece of ordinary life. The matching word for fathers is paternity, and parental covers both. In several countries the length of maternity leave is a live political argument. The related adjective maternal describes motherly feeling or the mother's side of a family.
