Sūra al-Rūm (Arabic: سورة الروم) is the thirtieth and a Makki sura of the Qur'an in its twenty first juz'. Its appellation as "al-Rum" (Rome) is because it predicted the defeat of Romans from Persian and then in a near future the defeat of Persians from Romans. The word, "al-Rum", appears at the beginning of the sura after the disjoined letters (al-huruf al-muqatta'a).

Sura al-Rum talks about the promise of divine victory and the journey in the world and in one's self or soul. It also explains some legislative (tashri'i) and existential (takwini) laws, such as marriage, innate love and mercy within human beings, helping those in need, and prohibition of usury.

A well-known verse in the sura is al-Fitra Verse concerning the divine nature and the type of the human creation. According to this verse, people have an innate or intrinsic tendency to God and religion.
