The constitutions of a number of countries contain such a clause but may define or interpret the term natural-born citizen differently. Many countries specify citizenship since birth as a requirement to hold certain offices. This is often described using the natural born phraseology and sometimes further qualified as requiring physical birth within the country's territory and/or requiring that one or both natural parents be a citizen of the country at the time of birth.
