Coalition for a Solidary Europe (Spanish: Coalición por una Europa Solidaria, CEUS) is an electoral list of regionalist parties that was formed to contest the 2019 and 2024 European Parliament election in Spain.

[2][3][4][5] The Basque, Catalan and Galician nationalist parties maintained a long alliance in the elections to the European Parliament, which began in 2004 with the Galeusca–Peoples of Europe coalition.

[7] On March 15, 2018, the Canarian Coalition (CC-PNC) and the Basque Nationalist Party (PNV) announced a commitment to repeat their electoral alliance for the European elections the following year.

[13][14] The Catalan party United to Advance, successor to the defunct Democratic Union of Catalonia, partner of the previous European coalitions, negotiated its entry into this list and, although it finally ruled it out, created a platform to support the candidacy.

[15] Josep Antoni Duran i Lleida, historical leader of Union of Catalonia and member of United to Advance, requested a vote for the coalition promoted by the PNV.
