The City Council of Seville (Spanish: Ayuntamiento de Sevilla) is the top-tier administrative and governing body (ayuntamiento) of the municipality of Seville, Spain.

In terms of political structure, it consists of the invested Mayor of Seville, currently Juan Espadas, the Local Executive Board (Junta de Gobierno Local), the deputy mayors, and an elected 31-member deliberative Plenary (Pleno) with scrutiny powers.

If the Mayor leaves office ahead of time a new voting may take place among the plenary members in order to invest a new mayor (meanwhile, another local councillor, conventionally the first deputy mayor, may act as acting Mayor).

The current mayor, elected on 28 May 2023, is José Luis Sanz of the PP.

The building, whose construction started in 1521, features a distinctive plateresque style.
