Yes if you're a Muslim yourself you may do so by your mutual will. But if not, it is an Islamic rule for muslim women to marry only Muslim men, and for Muslim men, they may marry among women of other religion who are from the people of the book, that is Christians or Jews. If you are a woman yourself, regardless of your religion, it is against Islamic Law for you to marry a Muslim woman.
