Omar/Umar (Arabic: عمر) is a masculine given Arabic name, which is represented in Islamic traditions. The name means “flourishing, long lived”.
After the emergence and military success of Islam, which was partially due to the second caliph Umar ibn al-Khattab (also spelled Omar, r. 634–644), Umar or Omar became a common name in Arab and Muslim populations in general.
The name is also used in Spanish-speaking countries, as Spain had a history of Islamic civilization for centuries, and among Jews (usually as "Omer").[citation needed]
The name Omar (spelled as Ómar) is also popular as a man's name in Iceland, and to a much lesser extent in Nordic countries.
The name can also be a variant of Ottomar or Othmar, a Germanic name consisting of elements *aud, meaning wealthy, and *mari, meaning fame.
