Riunorese Leonese is the name given to the Leonese varieties spoken in Portugal belonging to the Senabrese dialect. The name Riunorese stemming from the main village where said varieties are spoken, Riudenore.

Being in between Galician, Portuguese and Leonese speaking areas, many people consider it a transitional speech between Galician-Portuguese and Asturleonese, just like other regions between Galicia and Leon/Asturias. In other contexts, it's considered an "influenced zone", like the Extremaduran and Cantabrian speaking areas, by Castillian influence (which are also considered transitional speeches sometimes).

The writing system most commonly used for Riunorese is based on Portuguese orthography, with the existence of ⟨â⟩ ⟨ê⟩ ⟨ô⟩, the representation of [t̠ʃ] with ⟨tch⟩ (since Portuguese lacks [t̠ʃ], and ⟨ch⟩ represents [ʃ], unlike Spanish and other Leonese dialects, where ⟨ch⟩ represents [t̠ʃ]), among other aspects. The writing system has no legal recognition and is not regulated by any institution. The subdialect has a proposed writing system since it is the only Leonese-speaking territory of Portugal (considering Leonese a separate entity from the rest of Asturleonese, as Mirandese is an Asturleonese language/dialect spoken in Portugal in greater numbers).
