Mohammad-Reza (, also spelled as Mohammad Reza, or Mohammadreza) is a popular male given name in Iran. Mohammad and Reza are both Arabic names which are popular in the whole Muslim world. However, the usage of the compound given name Mohammad-Reza is mostly popular in the modern Iran (mostly among those who are born after 1926, when Reza Shah was crowned and his son, Mohammad-Reza, became the crown prince).
