The Toloño (Basque: Toloño mendilerroa; Spanish: Sierra del Toloño), also known as the Sierra de Cantabria, is a mountain range in the province of Álava in the Basque Country in northern Spain.

From the west, the range rises from the Conchas de Haro where the River Ebro enters the region of La Rioja at 445 metres above sea level, and from there runs east forming the northern border of the Rioja Alavesa, separating the Rioja region from the rest of Álava. Its highest point is Mount Toloño at 1271 metres above sea level in the municipality of Labastida.

It is noted for its steep rock faces on the southern side, and extensive forests in the north. The range is a landmark visible throughout the region.

The name

The Basque official name is Toloñoko mendilerroa, while in Spanish it is Sierra del Toloño. In Spanish, Sierra de Cantabria can be used too as a name, but the Instituto Geografico Nacional (Spanish National Geographic Institute) changed the official name in 2018.

From west to east:

• Peña Las Doce (1252 m): "twelve o'clock peak", the name comes from the shadow it creates at midday.
• La Tortuga (1255 m): "the tortoise", named for the shape of the rock at its peak.
• Peña del Castillo (1262 m): so called because a small castle was once situated here. Access is difficult.
