Radical Civic Union

The **Radical Civic Union** (, **UCR**) is a major political party in Argentina.

Founded in 1891 by Leandro N. Alem, it is the second oldest political party active in Argentina. The party's main support has long come from the middle class. In many occasions, the UCR was in opposition to Peronist governments and illegal during military rule. Since 1995 it has been a member of the Socialist International (an international organisation of social democrat political parties).

The party is not currently in any coalition since Juntos por el Cambio's dissolution in 2023.

## Leaders

The UCR is headed by a National Committee; its president is the _de facto_ leader of the party. A national convention brings together representatives of the provincial parties and affiliated organisations such as Franja Morada and Radical Youth, and is itself represented on the National Committee.
