The Osl are an old Hungarian kindred of the Rábaköz, the plain between the Rába and the Hanság, with their name-place at Osli and their later centre at Csorna.
If the English Wikipedia list is right, their man Benedict is governing Croatia, Dalmatia and Slavonia for Emeric as ban on 1 January 1200; but the ban's identity is disputed (see Ban Benedict and Ispánság of Zala), so the kindred's part in the brothers' war is not pinned. Its estates in 1200 are thinly recorded; the Premonstratensian provostry of Csorna is held to be their foundation (date not pinned).
Who he is
- Name
- Not pinned for 1200. The English Wikipedia ban list names Emeric's ban of 1199-1200 'Benedict Osl', which would make him the kindred's leading man; but Kádár (2018) identifies that ban with Benedict son of Korlát and Zsoldos (2011) with the palatine Benedict of 1202-1204
- Title
- Kindred (nemzetség) of Osl
- Family
- One of the old Hungarian kindreds of the Gesta, of the Rábaköz in Sopron and Győr counties. Later lines: the Kanizsai (from Thomas of Csorna), the Ostffy and the Viczay.

Places of note
- Osli: The kindred's name-place.
Where the sources disagree
- The ban of 1199-1200 is 'Benedict Osl' in the English Wikipedia list but Benedict son of Korlát in Kádár (2018) and the later palatine Benedict in Zsoldos (2011).
Evidence: The kindred's 1200 estates and men are not documented in the sources checked; the link to the ban rests on one list.
