15th Senate of Spain

208 (of 266) members of the Senate of Spain were elected in the 2023 Spanish general election to sit in the 15th Cortes Generales.

Election process
Most members of the senate (currently 208 of 266) are directly elected by the people. Each province elects four senators without regard to population. Insular provinces are treated specially. The larger islands of the Balearics (Baleares) and Canaries (Canarias)—Mallorca, Gran Canaria, and Tenerife—are assigned three seats each, and the smaller islands—Menorca, Ibiza–Formentera, Fuerteventura, Gomera, Hierro, Lanzarote and La Palma—one each; Ceuta and Melilla are assigned two seats each.

This allocation is heavily weighted in favour of small provinces; as the most populated province Madrid, with its 6.5 million people, and Soria, with 90,000 inhabitants, are each represented by four senators.
