Ammar is an Arabic name from the root amara, which covers both "long-lived" and "builder", in the sense of someone who builds up and fills a place with life. Ammar ibn Yasir was one of the earliest companions of the Prophet Muhammad, which gives the name deep roots among Muslims. In the United States Ammar has moved from number 1,609 in 2000 to number 1,241 in 2025, its best rank in this period.
