Sunan al-Darimi (Arabic: سنن الدارمي) or Musnad al-Darimi by `Abd Allah ibn `Abd al-Rahman al-Darimi (181H–255H) is a hadith collection considered by Sunnis to be among the prominent nine collections: the Al-Kutub al-Sittah, Al-Muwatta and the Musnad of Imam Ahmad.
Despite its title as a Musnad, it is not arranged by narrator in the manner of other Musnads, such as that of Tayalisi or Ibn Hanbal. It is arranged by subject matter in the manner of a book of Sunan, like the Sunan Ibn Majah.
Darimi transmitted these hadiths to `Isa ibn `Umar al-Samarqandi; date of death unknown, but presumably after 293 AH. Thereafter it passed to:
- `Abdullah ibn Ahmad ibn Hamawiya al-Sarkhasi (293–381 AH)
- `Abd al-Rahman ibn Muhammad ibn Muzaffar al-Dawudi "Jamal al-Islam" (374–467 AH)
- Abu'l-Waqt `Abd al-Awwal ibn `Isa ibn Shu`ayb al-Sijizzi (458–553 AH)
