Muhammad is an Arabic name that means "praised" or "praiseworthy", from the root hamida, to praise. It is the name of the Prophet of Islam and, counting all its spellings, probably the most common given name in the world; boxer Muhammad Ali is its best-known American bearer. In the United States this spelling has climbed steadily from number 618 in 2000 and number 365 in 2015 to number 239 among boys' names in 2025, a new high.
