Limburg-Styrum-Styrum was a County of medieval Germany, based in the Lordship of Styrum in modern North Rhine-Westphalia.
Limburg-Styrum-Styrum was a partition of Limburg-Styrum in 1644.
When the line of Limburg-Styrum-Iller-Aichheim became extinct in 1800, Limburg-Styrum-Styrum failed to inherit it and the Imperial Estate of Gemen, which instead passed to the Barons of Boyneburg-Bömelberg.
In 1806 Limburg-Styrum-Styrum was mediatised to the Grand Duchy of Berg.
The line itself became extinct in 1809.
